Me and my ex were really good friends in the past, we started online dating, we messed up, and then we broke up after 11 months of relationship. She was one of my closest friends before we started dating. It's been almost 2 years since the breakup, and i'm still not able to get completely over her. I find myself thinking of all the good times we had, wondering what would have happened if we didn't break up... that sort of stuff. We started talking again a few weeks ago, and at the beginning she was treating me really nice and she was bring quite friendly to me, she said she missed talking to me and that she enjoyed talking to me. But now, she is a bitch to me most of the time, and even though she is a bitch to me, i can't leave her because i still have the tiny hope that she will like me again one day and we will get together. But that hope has been becoming smaller recently, because she seems to be avoiding me and making me feel like shit on purpose, and that affects me more than she can imagine, because i still have feelings for her, and the bad stuff she does to me hurts. It hurts a lot. I'd really appreciate any advice, cause i don't know what to do anymore.
