I'm not attracted to my girlfriend anymore
Is there a reason why you aren't attracted to her anymore?
She's a boring girl who never tries anything new, different or cool.
Attraction is important in a relationship. If your partner isn't willing to change then you should break up.
She should be glad I didn't dump her ass when she was hot because her personality was the same then.
That is the reason why people should look past looks when going out with a person. Attraction involves more than looks and it is hard to be with someone when you are no longer attracted to them. Do think about that in your next relationship.
