Most Helpful Girl
If a woman is interested in a guy, why does she refuse to do his favorite things?
Probably because being interested in a guy doesn't necessarily equate into being a doormat for him. I find when guys are interested in a gal that doesn't mean he's going to do her favorite things unless they are things he also enjoys.1

She may have been told that it is beneath her to provide favors for someone she cares about. This is completely false. People who love each other take joy in providing for the other.
A successful relationship hinges more on what you're willing to give that what you think you can get.1
