To be fair, it's her fault she didn't just say she wasn't interested in the first place, she was leading you on. I've crushed on people in relationships, and it can be hard, just try to find something/someone you like more. And if you have strong emotions try putting them into something useful. When my mom went through rough breakups and was sad/angry she would work really hard or clean her room.

Well, you'll probably go through something similar to the five stages of grief. But I saw how they acted and then crawled back to the other person saying they were trying to make you feel better. It was sort of hurtful for them to say that in such a way. Even if you're sad right now, I hope later you realize you probably deserve someone better, who wouldn't lead you on.

you do deserve better

I agree with abc
