I just need to vent and I don’t have friends so.....

So I’m married......I got married May 26 2018 but a month after I found out my Husband was cheating and the other woman was pregnant (due January 2019 but the baby past away) on top of me finding out I was also pregnant. I also found out she was the one sending me nasty messages about my son D’Marco who past in February 2018. So I left him I put his ass out. And we would only talk sometimes if I texted him letting him know how my doctors appointment went. So he started dating this girl ok cool but he won’t divorce me he keeps telling me that he loves me and he wants his family back. So recently we started talking and messing around no big deal but he has recently asked me can he come back home and he’s leaving the girlfriend. He sent me a video of they texting and him breaking up with her but I’m still unsure of it. I’m currently 34 weeks and some days I get induced on the 22nd of March I’m also about to have a 2 year old in four days. He keeps asking to come home and keeps saying before I have the baby he’s going to be home. He bought my son a dog (my baby loves animals) for bday present and said “looks like I’m gone have to be coming over to help take care of the dog and train it and help you get ready for the baby. We been knowing everything since we were kids I was his first. He keeps saying all these things but it’s hard to believe him I told him he gone have to show me. What do you ladies think??? I don’t wanna give up on my marriage but I don’t wanna look stupid either. I told him he can’t walk in and outta of my kids or my life because he’s feeling scared and whatever the case maybe.

Now this is the message between him and friends. Him talking about wanting his family back and how she not on her shit

I just need some advice ladies.
