Kyle is annoying
Personally I don't blame the real Alexia for dumping Kyle. He is too much of a "nice guy". Overly complimentary and too into Alexia, dishing her food, always hovering around, actually bringing her a wrapped teddy bear at lunch, etc.. Plus he gets back together instantly with her after being called a sick puppy which shows he has no self respect or backbone.
Now there is nothing wrong with being a caring, faithful, boyfriend. But girls want an alpha male with backbone and his own sense of self outside of the relationship who they can respect. Not a kiss ass pushover. Yet Hollywood keeps portraying the "nice guy" as the one who gets the girls when they are the ones who do terrible with women in real life.
