1. You know what your partner needs to feel loved -- even if those needs are different than yours--Some people feel loved when their partner brings them a cup of coffee in the morning. Some need their spouse to tell them how beautiful or handsome they look. Others require sex and physical forms of affection. The point is each of us has different preferences when it comes to giving and receiving love. We have to teach our partner to love us and not expect them to read our minds.

2. You fight, but you do it productively--Conflict is a natural part of any relationship, but how you handle those disagreements can predict whether or not you'll be together in the long-run. How both of you behave now when you have a disagreement also says a lot about how you will or won't resolve problems in the future. A good relationship is one where the two of you fight fair. In other words, you don't curse, scream, talk down to each other or dismiss each other.

3. You get a confidence boost from your mutual physical attraction--Feeling sexual attraction and sexually attractive is huge. This helps boost your self-esteem.

4. You two are different enough to keep things interesting, but you're on the same page where it matters most--They say that opposites attract, and while that might be true at first, it's not a long-term predictor of relationship success. It’s okay to have different interests or movie likes, but similarity in key life values (views on money, religion, how you raise children) is what keeps people together over the long-term.

5. Your family and friends give the relationship their stamp of approval—Your family's approval of your significant other does matter. High levels of social support from your nearest and dearest are crucial to a happy marriage.

6. You feel comfortable getting a little adventurous between the sheets--Couples in secure relationships can combine spontaneous acts of intimacy with tender expressions of their love. The best recipe for great ongoing sex doesn’t seem to be finding more manuals to get bigger and bigger orgasms but tuning into each other and feeling safe enough to go with the thrill when it comes.

7. You are willing to put the "we" before the "me"--A commitment to doing what is best for the relationship is a strong predictor of future marital satisfaction. People who are marriage-minded should look for a partner who talks and thinks in terms of “we” not “me.” Someone who talks about shared dreams, shared values, and a willingness to put the relationship above his or her desires. Couples who put their marriage above their own desires are more likely to flourish.

8. You find yourself missing your partner when he or she isn't around—It’s important to miss your partner when he or she is away. If they are “out of sight, out of mind”' that’s not good. But if you have an emotional response to him or her being away, it's a signal that you really want to be with him or her.
