Can expectations hurt the people you love?

I don't want to make another person carry my expectations. If I start thinking, “I did this much for you, so you should give this much back,” my love starts turning into something heavy. I don't want to be self-righteous or pushy about it. At the same time, I don't want to forget what other people have done for me. I still catch myself sometimes and think, “Damn, that wasn't how I want to live.” When that happens, I apologize. Then I try to show what I mean through what I do next. That's about all I can do.
