Encouraging words needed.

I don’t really know where to start. I am a mother of 2 they have the same father. My first child was a birth control baby, the second was planned. We got married for what I thought was love he was telling everyone I deserved it. I really care about him so much. Even before we were married, when he had a job that didn’t pay too well, I loved him for his personality and I was ready to wait to be with him forever in life. Then he cheated. I forgave him because we were on and off for a while and I felt it was because I kept my 1st child when he wanted me to get rid of it and we wait until later but I couldn’t because I myself couldn’t bring myself to do it. I was scared. So time went on and he married me. Shortly after I started to see inappropriate messages from girls pop up in his notifications while we would be watching videos on his phone and he’d swipe them away really fast but it was already in my head. I still forgave him and the trust remained because I believed he wouldn’t do it again. It continued to happen throughout the pregnancy WE planned together months after getting married. His female best friend was sending him nudes (this woman asked to be invited to the wedding but we ended up going to the court house instead). I started to confide in an old male friend about what was going on in my marriage asking for advice on what I could do to be better as a wife to make my husband not want to step out which infuriated my friend because he said I was putting myself down and my husband found out and thought it was more than that and I let him know it wasn’t then blocked my friend. Since I had no one to vent to anymore I became anxious and untrusting of my husband so I would look for things that indicated he was stepping out. It got out of hand to the point I was calling to check with the people he said he was with to see if he was really there which 8/10 times he wasn’t. He found out and was angry. Fast forward we made up and I fell pregnant almost immediately after healing from the 2nd child we planned. He leaves and says he’s picking someone up from some job related venture come to find out that was not true and I just asked why did he have to lie he could’ve just told me he needed alone time and he said we’ll talk about it later so I let it go. I was going through depression due to a family member I was close to dying and I just wanted him home with me and the kids and he couldn’t even do that and after I told him what I was going through he said he wanted a divorce and that we are separating and didn’t return home. I am devastated but knew it was coming because trust was gone but what I didn’t expect was that he would stop checking on and visiting the kids and tell me he wants nothing to do with our 3rd child that I am currently pregnant with in the early stages. He doesn’t want to know the gender or be at the birth. He said he wants me to abort it and if I don’t he doesn’t want to deal with me and the kids anymore. I feel he will change his mind about the other 2 but he’s adamant he wants nothing to do with the 3rd one even though they are all his, I never stepped out. I can get over him but I can’t stop crying for my children they deserve better than this. I’m not keeping them away from him he just doesn’t come around. And I’ll never bash him to my children regardless of everything. I grew up with a father figure in my life and I really want my kids to feel the same love. I just need encouragement to push through and advice to show my kids as much love as possible so they don’t even notice the love they lost from their dad. Please be kind in the comments I know we are both at fault I take responsibility for my part in all this.
