My ex husband is engaged. How do I get him back (long and complicated but desperately seeking advice)?

• I met my ex husband 4 years ago and we got married 5 months into the relationship. I had gotten pregnant and he wanted to do the honorable thing and get married. I was already completely in love with him and accepted. His family greatly disapproved because of the age difference (I was 29 and he was 17) and his grandmother even told me on our wedding day she'll see that we divorce, so I feel they were a big reason we divorced. After I had my son, they were all in his ear to get a DNA test saying my son didn't look like him. We got the test 2 weeks after my son was born and it said that he wasn't the father. He said he was going to stay anyway, but of course his family members said he needed to leave and that I'm a whore and stuff, which I'm not. I didn't cheat on him, we had broken up for like a week and I hooked up with another guy but I didn't think the other guy was the father because we used a condom and me and my ex weren't. So after a month, he said he wanted a divorce and just up and left me and my son. Then his b*tchy grandma actually called me to say "I told you so." I tried calling him to get him to come home, but like a week after he left he met her. He moved her into his house after like 2 more weeks and told me it was over for good and changed his number on me. I know I'll never love anyone like I love him. I was living with my parents at the time and 6 months later, he comes knocking at my door. He says that she kicked him out because a) he was then on drugs and b) she found out we were still legally married. He told me about how sad he was about losing her and that she was pregnant. I told him she doesn't deserve him, I mean she threw him out of his house and she's pregnant with his kid? What type of woman does that? So he lived with us 4 months and then actually went back to her. I fell in love with him all over again and I couldn't lose him again. I called him everyday and he said that he was grateful that we helped him get clean, but that he needed to be with his family and then he filed for divorce. I was depressed for months. I ran into him again 6 months later at a party. Word on the street was that he was single again. I was flirting with him at the party and we ended up having sex at the party. He says that we didn't have sex and that I was drunk, but that's untrue. I had a couple drinks, but I wasn't drunk. So I find out I'm pregnant again and I tell him. He says we never had sex and to leave him alone. Then, I find out she got pregnant around the same time. They weren't even together and he was around for her and her babies and not me. It turns out that he's not my daughter's father, but I'm confident we had sex that night. So now it's been a year since the babies have been born and he's back with her. I read on Facebook that they're engaged. He meets me a few days ago and says I need to move on with my life and that he's in love with her. WTF? She's a little girl, (18) and kicked him out when he needed support and he's in love with her? It's not fair that he just pop in and out of my son's life like that. We're both grown adults and he's choosing to deal with a baby with babies over me. I'm not going out like that. I need him in my life and I won't stop until I have him back. How do I get him back and away from the baby momma?

  This sounds like a bad episode of Jerry Springer. All of you should just stay away from each other
