Broke up with him- Did i make the right call?

Last night I broke up with my boyfriend/ father of my baby. I think it was the right call, but part of me can’t help but doubt myself and feel badly for ending it.

A little backstory is him and I started hooking up in November of 2018. We were basically friends with benefits as both of us had gotten out of long term toxic/abusive relationships in June 2018. However I guess he went back to his ex like a month or so after they broke up and she ended up getting pregnant. I had no idea she was pregnant with his baby when we started hooking up. I didnt find out until end of February 2019 when she was already very pregnant. Of course I was a bit mad because he didnt tell me& i didnt want to be the “side chick”. But he assured me they were broken up. We still stopped hooking up because things were obviously still complicated with his ex. He had his baby in the beginning of May 2019 and around September we started up again.

Then end of November I found out I was pregnant by him. I told him and he asked me to have an abortion. I really tried, I went to the appointment, i was on the table about to have the D&C when I stopped the doctor. I apologized to him and let him know he was under no obligation to be there for me or the baby or provide financial support. He decided to be apart of the pregnancy and baby’s life. So the whole pregnancy we acted like a couple, he admitted to having feelings for me, and I him but he never asked me to be his girlfriend. He said he was still traumatized from his ex because of how she abused him. And I understood , my ex was horribly abusive as well so I tried to be patient. But he never told anyone I was pregnant. Not his family, not his ex, no one. My family knew and he met them, hung out with them, but no one on his side knew about me. Then my mom threw me a drive by baby shower and told him, but he didnt show up. And for the birth (which was a scheduled c section) he wasn’t there. He had work but come on it was scheduled he could’ve had the day off. I guess this upset me more because he told me he was there for his ex the whole time even though she was in labor for 30 hours and he worked then too. Also his family knew about the baby from the beginning. And yet with me he wasnt there and didnt tell anyone.

After I gave birth I’m the one that made it official between us. This was 2 months ago. And since then he still didn’t tell anyone. His ex found out by stalking my page, and she told his sister but that’s the only reason they know. And only the ex and the sister know. Not his parents or anyone else.

His ex also blows up his phone and gets mad when he’s here. Which to me I didnt get because an ex is an ex. So I asked him why it bothered her so much that he has another baby and he just said he didnt know. I went on her page for the first time and saw she had pictures of him, her and their son together, had pictures of him asleep in bed from this year, and a lot of posts of him as if they were still together. His excuse was “i cant control what she posts”. So i asked him when was the last time he had been with her. Like when was the last time he went back and hooked up with her . He said he didnt know. I asked if it was after she had their son and he said yes, then I asked if if it was after I got pregnant like while I was pregnant this year. He just stayed quiet and said he didnt know. But how do you not know the last time you fucked someone? Especially if im asking about recently. He just kept saying he didnt know, even after I told him to just be honest. And then he said he didnt like thinking about it. I took that as a yes and told him I didnt think we should be together if he couldn’t even be honest and especially if that meant he had been with both her and I at the same time. Basically living a double life. He just left. And I haven’t heard from him today.

Did I overreact? It just seems like he’s been with her the whole time. The way he’s been hiding me (which he claims he hasnt even though he hasnt told anyone) , the way he gives in to her, the way he couldn’t answer a simple question. Idk . Maybe I have no right to be mad.
