Most men suck

I been with hubby since 16 married since 24. I'll be 31 in august. My first love and we have 3 children and one on the way. He has another from cheating on me with my uncles ex. I keep asking myself how do I stay? He doesn't love me and the kids. He loves his son with the other woman more. He's verbally abusive and quick to walk out on us. How do I just move on? I want to be strong too like the posts i read on here of women leaving. I am afraid. He's all I have besides my kids. No family to support me. I wanna die inside but my kids. He knows leaving kills me. We don't live together anymore. I kicked him out Last October. After ttc for 6 years I got pregnant when I gave up. 23 weeks today. I love this baby but I just want to be done with him! He's in my system. He's all I think about. I can't see myself with anyone else because I don't wanna start over but I know he's not the one for me anymore. Any advice? Please don't be harsh I'm an emotional Hormonal pregnant women.
