Too strong or maybe weak

I don't know where to start. I'm pregnant by a man I would say has been in my life for almost 7 years. However, we've been on and off for 5. Towards the end of those 4 or 5 years, he cheated with 2 girls and I mean that because they were basically just hitting 20 and at that time his grown ass was 25/26. I didn't find out about that until a year later. It's probably been more females. Sad thing is, he had the girl over at our apartment and he drove my car to her dorm room to fuck her while I was at work. During those times we were doing good financially and had a nice apartment. I worked and came home to cook for his sorry ass to have dinner ready when he came home from working two jobs. We never went anywhere. He always wanted me to go out with him and his friends. So he would just hang out with them frequently over me. There were times I'd come home from work and his friends would be over. I ended up moving out and staying with family after quitting my job from stress and him going to jail. We fell behind in bills and were facing eviction. Then I ended up living back with him in a hotel after my family had to move. He had just got out of jail. That's when shit got real. I was so not in a healthy place and end up doing drugs with this guy. The one who swears he loves me. He was paying for the room each week and didn't ask me for any help. He just wanted me to save my money. It appeared that he wanted us to work out and pray and get back closer to our faith, ironically. But by then I was too damaged. Although he's never hit me, he's choked me and put me in a headlock. It was hard to accept that he's changed for the better. What was crazy is, he was a great listener, and would give me encouragement. Anywho, after us clashing continuously from my bipolar spells and not accepting that he has changed for the better, not to mention my attempt at suicide, my family came and picked me up and I stayed with them. He shortly after left to go up North to stay with his close friend he referred to as his sister. He ended up getting in a relationship with his friend's girlfriend's sister supposedly after we broke up. I believe he was already in a relationship with her before he left. I had no clue about this until way later when he ended up coming back and he told me. He came back to stay with me and my family because at that point he had no where to go. I later learned that the girl had broke up with him and most likely, that's why he had to go. Still, I was there. And writing this out, I realize just how stupid I sound and have been. Anyway, I end up pregnant. He swears he will be in his child's life and such. He's working and coming home every night but shows no desire to get a better job. Some days we get along and some days we don't. He ends up tackling me to the floor because I called him a bastard. Fast forward, I put his shit out because even though we weren't together, he showed no respect for me carrying his seed. He started staying out all day because he swear he needed peace because we constantly argued just to come home and go straight to sleep. No type of support or anything that's necessary during pregnancy. Just a few meals when he could "afford" it and provide a half ass rub down with an attitude. Sometimes, just sometimes, we'd watch a movie or documentary together. But now after putting his things out, he is trying to do "right". No calls, but he texts to see how me and his child is doing. He gave me some money to put towards getting some things for the baby. Now he's constantly texting me talking about working it out and etc. And I'm constantly reassuring him it'll never happen and from now on it's only about our child. I now realize EVERYTHING I've missed before, how naive and stupid of me. Now my child may be in an unhealthy situation. I've managed to get most of what he needs from consignment sales and Walmart. I sold my piece of shit car and was able to get a more reliable one, and finally, I landed a wfh job, well just a job in general. I stay with my sister which have also been stressful and have no idea how I'm going to wfh when my child is born in June since training extends past my due date. I've prayed and got this far and I have faith that this too will work itself out. I am hoping to be able to move out very soon with this job. I feel that although I've been weak from accepting this kind of treatment, I'm strong for overcoming it all. Everyday, I'm going through this by myself. I keep my cool and I stay focused on my goal. He appears to want to be in his child's life, I just don't know how we are going to do this co parenting. I don't even know my goal of writing this, but maybe someone have been through the same thing and have any words of advice. I may not respond to comments because of wanting to remain anonymous but all are appreciated.
