Mom vs my man, baby on the way

So, I need all of your opinions and what to do in this disruption. I don't want to sound like I am whining so I will let you know in advance that I am going to express some deep feelings here because I don't know where else to turn. So, recently, my boyfriend and I split because he found some texts between me and my ex whom I share a child with. My ex and I have had a lot of ups and downs but we have never gotten back together, nor do we share those feelings toward the other. We always try to keep it cordial, sometimes we're friendly, sometimes we hate each other. My boyfriend and I have been together for 2 years, in may and we have also had a lot of arguments because of my ex. It always bothers him when my ex and I argue, and he warned me once that if I kept on and chose to degrade myself to my ex, and stoop to his level, we will be over and he will leave me. So, recently, my ex and his new girlfriend had some drama and he came crying to me about it and I, listened. Then he began to vent to me about the girl who took him to child support for their 6 month old, and got $975 a month for it and followed by a nasty custody battle. Amongst our few talks, I encouraged him to try and work things out with her, and to work it out if that's who he loves. Needless to say, we were friendly and I should've stopped it but I didn't feel anything toward him but compassion and I felt sorry for his situation. So one night, in late April, my boyfriend and I were going to dinner and as soon as I turned my car on, and the phone connected to Bluetooth, my ex calls, he didn't have our daughter that night but I honestly l had nothing to hide, so I answered it, and he starts off with a flirty "what cha doinng?" My heart dropped not because he was flirty, but because I couldn't believe it was happening right then and there next to my boyfriend. So I tell him I'm heading out what's up and he's like well my car broke down and I simply told him I couldn't help and to call someone else. I hang up, and that was the beginning of the end. My boyfriend and I had a huge fight and he stated that for him to be soemone I fight with so much he certainly felt comfortable enough to call me for a ride at 11pm. I do not argue with him because if his ex called him so late at night I would lose my shit. I had no explanation l, but I apologized and told my ex the next day that any friendship we had is over and that I have always respected him and his gf and that he should respect my man to not ever call me for a favor like that. We made up, in early May, then a few days later he wakes me up one night letting me he went through my phone and found texts of me and my cousin and I was so mad at him while we were fighting and I trash talked to my cousin about him and he said he couldn't believe that his wifey would put him down that way to someone else and talk that way behind his back. Then he saw a text where I also told my cousin that I missed an ex boyfriend sometimes, a different ex, not my daughters father. But I don't mean I miss HIM I just miss how he used to treat me. He just said that all of it combined has brought him to the last state and that he's done and finest want to be with me no more.

A few weeks later, on may 25, we get a positive pregnancy test. We're broken up now, and we are moving out of our beloved home on July 31. I am moving back to my moms temporarily and he is going to his moms.

So today, I ask my mom if she will have a problem with him coming around sometimes to her house and she states that there is no reason for him to be in her house if he doesn't want to be with me, she's completely overlooking the events that led to our break up and she expected him to stay for the baby. She also states that she does not want his family at the shower and that I am forcing her to invite people she doesn't want there.

I told her that I don't agree and that I want him around. She said she wishes it were the way it was for my first pregnancy, where her dad abandoned me the entire 9 months and didn't show until she was 10 days old. I am very hurt and don't want to move into her house at this point. I am 27 years old and though I need to move there to save up and get back on my feet. This is a man who I want to be with and we are going through a tough patch right now. I don't know how to express my feelings to my mom, she stars that he won't even be allowed to my room or anything. And she doesn't want him in the house. When we split up, I wasn't working and still am not. So I have no choice but to go there in the meantime. I am afraid that this will only make things worse for me and my boyfriend and that it will be too hard to withstand this hard time. I am having his baby, how does she expect for him to not ever come around or to not be at my baby shower or gender reveal. Wait until she finds out he wants to be alone in the delivery room with me. I need advice ladies! Please help me .
