I'm having a hard time with the father of my child...?

I had my son in January, and me and my ex broke up in September. I had gotten pregnant rather soon after we started seeing each other...so we were only together like 6 months and i moved in once i found out i was pregnant. But slowly i started to realize there was something wrong. He has some emotional problems but his family could never get him to go for help without a fight and him disappearing for months. I think he's schizophrenic or severly bipolar. When we split he stalked me for months and literally ruined my life with rumors and accusations.(We live in a small town) I had a restraining order but then he backed off and i though we could at least be civil, but he took it as us getting back together and after all he had done to me there was no way, so he spiraled down again. He's put my whole life(as he sees it)on the internet for all to read. The judge has ordered supervised visits and a psych eval, he hasn't signed the BC yet though, should i walk away with my son?
