If that's the case, then u have a huge decision to make. First off, remember it's not the child's fault that this happened so don't put the child through hell. Second, this person sounds like a jerk so he isn't worth your time of happiness. If u would rather be happy than be miserable I would break things off.
If u need to blow off some steam about things (I know how that goes) just send me a message and blow off some steam. u don't have to, but it might help. Just label it Blowing off Steam of something. I'm not trying to sound harsh with my advice of anything though, so please don't take it like that.
