My GF still loves her ex, don't know how to deal with this...

Me and my GF have been together for about 3 months now. I love her alot but im in an uncomfortable situation. first of all, She knows I care about her a whole lot and love her to. I think i'm probably more into her than she's into me. I'm only the second guy she's slept with, we spend lots of time together and it seems like she enjoys being with me but i'm pretty sure (especially after we talked tonight) that she still loves her ex... Her ex is not a good guy at all, he took her virginity when she was very young (only 15) and he is 5 years older than her! They dated for 4 years and 1.5 years of it was long distance since they are both originally from a different country and she now lives in the US where i do. They broke up because he cheated on her during the long-distance relationship! I talked with her about it a little today since we are both starting to become more open and she says that it wasnt his fault and she didnt beak up with him because he cheated on her... she said it was because she wanted him to be happy with the other girl... I wish my GF would see her EX-Boyfriend for the piece of shit that he really is! i don't know what to do... I'm really upset about this and she wants to travel with me over spring-break. should i tell her i don't want to go anymore? I don't want to feel like i'm just being used for her to get over this guy.

If she still loves him, she isn't ready for a relationship with you, and you won't get what you want out of this relationship emotionally.
