I think I'm too used to being spoiled by guys?

This is perfectly normal for attractive women your age. If guys are stupid enough to think that they can get you to like them by buying you things or being nice to you, then that is their problem, not yours. That is why so many good-looking women seem like they are very rude. It is because it is the quickest way of getting rid of low value men. After being approached in one way or another by guys an average of five times a day, women just get annoyed by it and find ways to stop it. The choice of whether or not to accept their gifts is your choice.
