I’m stuck

After a year and a half of discussing how porn makes me feel unwanted when we aren’t having sex ourselves. I thought that’s all I had to worry about was his porn addiction this is the first time he’s ever admitted he had an addiction after the third time of him being caught. I know everyone has a different opinion on if porn is cheating or not I just think it crosses a boundary specially when you’re lying about it and hiding it. I have now found out that he has been emotionally cheating on me with past girlfriends past flings etc. he was sending girls nudes while I was pregnant and Sexting them.we’ve only been married a month we have a six month old baby and he admitted to me that he was emotionally cheating with them or other women basically my whole pregnancy. He said he would get mad at me because of the things I would say when we would get in fights and I would think we were all good and we forgave each other and he told me that he would be secretly holding onto things from weeks or months ago and I wouldn’t even know and he’s “ talking to women to get back at me “. He said that he’s going to get help and go to therapy and he’s done doing that and acts as if he can just shut off the addiction which I told him he can’t he needs to get help. I found all of this out February 15 but I had already known he was doing things porn wise but didn’t know the extent of it all. It is now March and he still hasn’t gone to therapy keeps telling me they need to call him back blah blah blah I just feel like it’s not my issue to make sure he follows through when I told him that was something that needed to be done to restraint our relationship. Of course we still live together and take care of our son and sleep in the same bed so I always assume he thinks we’re just back cool and everything just goes back to normal but it doesn’t. I’m so upset at myself for getting married to this man when I wasn’t 100% sure and that’s things I have to work out within myself as well. I’m not perfect I’m not saying I am perfect I just want my boundaries respected and I wanted to be respected if I say I don’t like something and you continually to do it over and over and over again you don’t care you don’t think that boundary is important. I don’t think watching porn makes someone weird or anything like that I just don’t do it and I don’t see the point of it especially when you’re not having sex with your partner. This is a porn addiction he would watch 10-11porn videos a day and he would tell me once everything was found out he wasn’t even watching it to get off he was just watching it to watch it and he just watch a couple seconds to keep watching videos and all of a sudden thinks that he can just shut that off. When I know in reality he’s just gonna keep finding ways to hide it better which he did and I was starting to trust him as soon as I do right back at square one and worse than we were before. I ended up reaching out to one of the women via Snapchat she said that she knew he was married but only found out because she went searching but he played it off as if we were just cool and our relationship was open etc. i’m just lost on what to do. I feel so stuck. Can you honestly change without therapy or weight therapy is it something that he can just shut off and all of a sudden want me 100% of the time. I just don’t think it’s fair that because of his actions and decisions I will miss out on my sons life. Even if we do coparent and share days those are days and night I miss out on my sons life because his dad is a pig. He keeps justifying that he didn’t actually cheat because He didn’t have sex with anyone but that’s due to the fact that we live states away from where we know everyone I feel as though if we did lived back home he would have cheated on me physically. Emotionally cheating hurts because you didn’t even give me the opportunity or chance to listen to you and give you what you need etc. we were still having sex almost every other night just to find out he’s talking to other women and still watching porn it feels as if I’ll never be enough. And of course now that he knows I can leave him he tries to say he loves adores me and will change.
