Your partner learns a lot from you about their needs in a relationship, and that's a good thing, although this influence in your romance might not be the most fun or easiest to handle. They have a lot to learn from you, in part because you're either older than they are or more experienced, and you have a lot of solid advice and guidance to offer to them. But they're very different from you; they tackle life's problems in a different way than you do, and they could see your advice not so much as guidance but as a restrictive influence on them.
You want to relate to each other as allies, but instead of being able to enjoy all the myriad ways in which you're different, you're both more likely to try to hold each other back from doing the things that you would never do -- or possibly from doing things that ultimately lead you away from each other. In any case, you probably stick together out of some sense of indebtedness, though that doesn't have much foundation in reality. What you really get from your relationship with each other is more about a sense of control -- on your part -- and of stability -- on your partner's.
