Unwanted.

Chelsie
My  now ex boyfriend just got back with his seconds child's mother. We had just gotten back together and I had just had sex with him the night before. Then he just blocked me on everything and stopped talking to me.  I'm in a bad head space right now did I do something wrong? How could not just tell me that this isn't what he wanted? Idk do you guys have any advice on how to get through this?
