Help!!!

So my fiancé literally just asked me “ why can’t you be like my homeboys wife’s” meaning why don’t I let him run around doing drugs, and whatever he wants. I did let him do that when we broke up for a few weeks he is now on house arrest and his homeboys are in jail. So why would I want to be like their wife’s? I’m 9 months pregnant with his kid and literally due tomorrow I’ve told him I’m feeling unloved and unwanted he just tells me I have something wrong with me or that what I’m feeling is stupid. What do I do? I’m due tomorrow, we live together and I have no where else to go. He does what he wants I just hang out at home and keep to myself. But guess he doesn’t see that.
