Most of us can do without a car if need be, but few of us want to do without love. Within most of us there is a basic human longing for connection and relationships with others. For many, the backdrop of a loving, committed relationship gives us the space to learn about ourselves and grow deeper as we age.

Like cars, relationships need maintaining and regular tune-ups. But because they don’t come with operating instructions, below is a simple maintenance guide to help you keep your love relationship strong, healthy and on the road for years.

Know What Kind of Driver You Are

Recent research has shown several things strengthen a marriage and other long-term partnerships: communication, honesty and spending time together. Just as important is knowing yourself and what you bring to a relationship. When you connect with yourself, and work on those challenging parts of yourself, you create a stronger and better partner for someone else. That isn’t just true in the first flush of falling in love, it's true for the many years that follow.

“Being intimate with ourselves is the necessary foundation for being intimate with others,” writes John Amodeo in Being Intimate: A Guide to Successful Relationships.

Too often, communication between long-term couples can devolve into the logistics of life: Can you pick up the dry cleaning? Did you take out the trash? Loving relationships need—and deserve—so much more.

Deeper communication may require an intentional shift or willingness to expose vulnerability. But isn’t your happiness—and your relationship—worth the risk? Here are some ways to begin:

Thank you for… Everyone likes to be acknowledged and appreciated for what they do. Thank your partner for more than just what you asked him/her to do. For example, you might thank him or her for being a great parent, for always making time for the children.

How and What to Reveal Writer Pat Love asks, “What is intimacy?” and then answers her own question, “Into me, see.” It’s not that to be intimate you need be transparent, or that every thought, feeling or story must be shared with your partner—but intimacy flourishes in a climate in which it’s safe to disclose parts of your experience that cut closer and closer to your private self.

Sometimes, though, a longing for connection can lead to disclosing too much too soon, or telling a new partner more than he or she is ready to know or needs to know. Or to opening up too much about ourselves or people close to us when discretion might be the better choice. Consider following the Rule of Three: let a disclosure come to mind three times before sharing it rather than saying everything exactly as it occurs. Those things that recur are the ones that really belong to the relationship.

Remember time is a necessary part of the intimacy equation. The thrill and power of the first weeks of a passionate relationship encourage self-disclosure and lots of sharing, but no matter how strong the connection, some things can come to light only after trust has been allowed to build.

Gratitude isn’t a new idea; most spiritual practices and philosophies emphasize gratitude and compassion for others. But in recent years gratitude has shifted from being an idea to a concrete tool that people can use to become happier and healthier. This practice focuses on appreciating what others have done for you and de-emphasizes being angry or blaming others for your problems.

“When we develop a sense of appreciation for those around us and cultivate a sense of gratitude for life itself, we are relieved of the burden that comes with seeing ourselves as ‘victims,’” writes Greg Krech in Gratitude, Grace and the Japanese Art of Self-Reflection.

Krech calls this state of appreciation “grace,” a term used in many religions. However, grace as a practice is not a belief as much as a shift in thinking. Or as Krech puts it: “It’s the difference between seeing life as an entitlement and seeing it as a gift.”

However it is practiced, gratitude isn’t a blindly optimistic approach in which the bad things in life are whitewashed or ignored. It’s more a matter of where we put our focus and attention. Yes, pain and injustice and cruelty exist in this world. But when we focus on the gifts of life, we gain a feeling of well-being. We often feel more energized to reach out and help others; we feel we have some power to positively affect our world. This again leads to a feeling of well-being…and gratitude. It’s a self-sustaining cycle!

Good personal boundaries make for good relationships. Boundaries are those invisible lines of protection you draw around yourself. They let people know your limits on what they can say or do around you. Healthy boundaries give you freedom in relating to others. Make them too solid and you build walls, too weak and you allow other’s actions to harm you.

It’s not always clear where our boundaries are or need to be. Recognizing and studying the signs of ignored or ineffective boundaries is a good place to start, as these “symptoms” give clues to the needed boundary. See if any of the following ring true for you.

Aloofness and distance. When you are unwilling or fearful of opening your space to others, or when you build walls to insure that others don’t invade your emotional or physical space, this may be a defense against cruel behavior, abuse or neglect that you allowed to happen. A person with healthy boundaries draws a line over which they will not allow anyone to cross. They recognize their right to say, “No!”

Chip on the shoulder. This kind of attitude declares, “I dare you to come too close!” and is often the result of anger over a past violation or ignoring of your physical or emotional space by others. Healthy boundaries mean you are able to speak up when your space has been violated, leaving you free to trust that you can assertively protect yourself to ensure you are not hurt.

The saying, “Words are cheap, action speaks,” is never more true than when applied to “I love you.” Whether spoken to a romantic partner, your children or other family members, if the actions aren’t there to back up the loving words, it all means nothing. Below are 10 of the best ways to say “I love you” in your actions. But there are thousands more. See how creative you can get in coming up with your own ideas.

1. Greet your loved ones with a big smile, a hug and a kiss.

2. Really listen to what your loved ones are saying; give them your undivided and undistracted attention.

3. Do simple (even random) acts of kindness, such as massaging shoulders or feet, cooking a favorite meal, running a bath.

Living with those you love—whether they be mates, children or older parents—brings intimacy and stresses that are different from other relationships. Here are 10 daily practices that help keep the love flowing and the relationships growing.

1. Share something from your day. Involve your loved ones in your life outside the home—or inside your heart.

2. Express gratitude. Show that you notice their daily contributions to the family and your life. Receiving a “thank you” for doing the dishes or taking out the trash feels soooo good!

3. Eat dinner together. Connecting with each other over food is an ancient human practice. It’s worth it to make time for this warming activity.

What do you want for dinner? and Did you take out the trash? may be two of the most frequently made comments, one partner to another, but in order to maintain intimate and loving communication in their relationship, couples may need to become more intentional in the messages they give one another. Try these.

1. Thank you for… People need to be acknowledged and appreciated for what they do. Not just for the things they’re asked to do, but just because.

2. Would you please… Expecting your partner to read your mind is expecting the impossible. Say what you want and need. Be specific.

3. How do you feel about… Asking, then listening to your partner’s response, withholding judgment or any need to try to change the feelings.

The poet Rilke once advised a friend that a good marriage does not create “a quick community of spirit by tearing down and destroying all boundaries,” but rather appoints the other “guardian of his solitude.” Rilke’s comments, applicable to all committed partnerships, point to the mutual respect and clear-eyed seeing that form the basis for genuine intimacy. Here are 10 ways to attain it.

1. Bring up difficult subjects.

2. Listen with openness to feedback.

3. Attempt to elicit a fuller range of feelings during discussions and disagreements.

Let’s face it: love is messy. With its magnified highs and lows, love is unpredictable and never what we expect—so much so that we might be tempted to cower in fear. But if we approach love with the courage of a warrior, we can have relationships of heroic proportions. Here are 10 ways:

1. Be yourself. If we want to be loved for who we truly are, why put on an act?

2. Don’t believe your stories. Our interpretation of events and feelings is, in fact, just one possibility for what is actually true. Focus on what IS to get closer to the truth.

3. Stop looking for perfection. More than likely, what we call “high standards” is a mask for our own feelings of inadequacy.
