Advice or run

So after almost a week of questioning and being hurt by my bf or ex I’m not sure yet, he finally exposed the truth to me. Or at least some of it. There is this girl he sometimes works with, at first it started out him calling her cute and what not at work. Well I asked him to stop talking to her bc that ain’t cool! Him and I got into an argument last Sunday and it was pretty bad. As soon as I left he hit her up to “vent”. Well long story short she ended up sending him pics of herself which was pretty inappropriate tbh. You don’t send him pics like that. I have the pics he sent to me. I knew there was something going on. Now he’s saying I can’t break up with him or whatever but the issue is, I’m 25 weeks pregnant and it took me talking about it all day every day for almost a week for him to come clean. He says he loves me and wants this family with me but tbh, I can’t do it. This is like the 5th girl that he’s involved we haven’t even been together a year. I just feel like I’m doing myself wrong and I’ll never be able to trust him. Like I literally am starting counseling bc being pregnant and going thru this is extremely hard for me to do. I can’t even do it ladies! Also this girl has threatened me with going to court for defamation of character and a bunch of shit for actual things that she’s been doing. Like he told her I think she wants him and stuff, I just feel like he’s trying to fuck with my life by lying and what not to me. Idk what to do sometimes like I need help with it.

It’s so hard leaving that’s why I’m going to start therapy. And tbh I wish I had known him a lot better before getting pregnant but I will never regret my baby. He’s a blessing to me. I’ve always thought I couldn’t get pregnant. So I guess me not being careful but I’m due in June and it feels like me being brainwashed into wanting to believe for the 100th time he will change. It’s like he’s convincing me he will change but idk, he is so apologetic but also I feel like it would happen again. That’s why I’m so hesitant about giving him another chance. I don’t want to disrespect my own self, and I also am a very smart person. Mainly I come on here to vent and get validation bc he has made me feel so crazy.

This was an unplanned pregnancy but you know what just stop you sound ignorant. Shit happens. I’m old enough to take care of my baby. My baby will be well taken care of and loved. That’s all that matters. Even if it wasn’t a planned pregnancy a child is a blessing a gift from god that I’ve been waiting so long for. Do you know how long I’ve suffered from infertility? Many many years so you know just bc the bf is whack, isn’t my issue anymore. You don’t even know the whole story so please stay off my post with the negativity.
