So.. the guy I like likes me to but he hassnt asked me out and got back togeather with his ex who cheated on him... what happened? :(

For sure he likes you but is he willing to be in a relationship with you? He got back together with his ex so possibly he was in the fence between you and her... he chose the familiar route.

Well sometimes old feelings are stronger then new ones especially if you haven't made any strong attempt to get together. My girlfriend cheated on me and I went back to her cause my emotions took control over my logic. Some guys don't know what's good for them and it takes a lot for someone to make them see that. Good luck and if your feels are strong try talking to him about it and make it known what you think is best

It would say that he was not over his ex yet, he may have liked you, but he was not over her yet.

He may have liked you but is still hooked on his ex. That's the way it goes sometimes.
