My husband is crazy

We have been married for 3 months and I’m 24 weeks pregnant. He has bi polar and schizophrenia. The last month has been hell on earth from his highs and lows. He has threatened find him another woman that will please him because I don’t want to have sex all the time. I’ve tried to explain to him that it hurts and I think it may be have a UTI or something. None of that matters if he can’t get what he wants he starts talking crazy to me. I can’t take anymore. I made a vow but I don’t want to bring an innocent baby into the unstable environment. Plus I have no where to go really.
