This is up to you. I wouldn't really be asking these questions to other guys who don't quite understand the situation. My advice for you is the following, though.
If you break up:
Don't feel guilty just because she's given up - if you weren't really reciprocating then this was bound to happen. Feel good about the fact that she will get over it and find someone who really, really likes her and can show it.
If you stay together:
First examine if you REALLY like this girl- to me it sounds more like you were semi-guilted into having feelings for her rather than this being a spontaneous kind of thing. If I'm wrong, then work on spontaneity in the relationship, take her out on dates, make it a game again rather than taking her for granted. Easier said than done.
