Well, do you have an idea if it's a medical condition (sometimes that happens... like with depression), or if it's just that she doesn't see you that way anymore, or she's going across town for some action-satisfaction, or is it a "talk-it-out" kind of problem?
The only one that you probably can't fix is if she is going across town. To me, I couldn't take that.
Maybe I'm prying too much into your personal life here. I apologize if I am.
