Ok sweetie. Take a deep breath. You are not stupid. Again, YOU ARE NOT STUPID. There will be a man out there that is not an addict or an abuser and he will love you and your six kids. But, you need to work on you first. Figure out why you are picking men like this. Does your ex H pay child support? No contact for a little while, at least until the baby is born may be ideal. Then you may want to let your hormones get back in sync. I would try to find time for therapy if you have any to spare. But I would suggest you maybe can use the time you spend taking care of him and put that time in therapy?
You can do this. I can feel it in your writing. You are stronger than I am, because I don't have it in me to hardly do one job, let alone 3 while pregnant. You are a strong person. Please believe that!!
