Dated a girl exclusively for a few months. Recently she ended it saying "she's not crazy about me like she should be". Clearly I was doing something right because we were sleeping together for four months. I didn't magically become too clingy or whatever, I treated her right, let her know how I felt. There were no games. And she reciprocated. Until she didn't. She didn't hide behind a wall of excuses she was real. I'm struggling to understand how it can just flip on a dime, when nothing I did shifted? But I want this girl back, wanna chase her. My heart says she's worth it my head knows life doesn't work that way. Someone talk me out of it or into it?

Tldr; what did I do wrong? Can I get her back
