I’m pregnant and moving to Flordia leaving my Baby Daddy Behind.

I (28F) am 13 weeks pregnant. I found out when I was 4 weeks and told my BBD (27M) right away. Me and him were never really in a relationship yet we were exclusive or so I thought. I loved this man so much I’d do anything for him. I always thought we would end up together eventually. He was my best friend. My rock. We weren’t together but he always treated me like his gf. It was very confusing. When I told him I was pregnant I thought that was it. We’d get together and work as a team to raise this baby. Give her a chance to a two parent home. But no, instead he told me he was getting back together with his ex. I thought he and his ex were long done but to my surprise they never broke up. He was juggling both of us for MONTHS. I was absolutely devastated. He told me he had told her about his unfaithfulness and that she forgave him. That she was all in and was willing to see our child as her own. I think this is absolutely crazy. What kind of woman with any sense of self respect would just accept this and continue to be with a man like this? In the end he chose her and even though I was pregnant with his kid he came around less and less. Especially when I needed him the most. My first trimester has been lonely and I’ve struggled by myself. I contemplated getting an abortion but I couldn’t do it. He just started to come around recently to help. He buys me groceries or washes my dishes because I can’t. I’ve talked to his gf and she is all in. It’s just crazy. I don’t hate her because in the end we were both lied to by him but I despise him. I don’t trust him. I honestly don’t believe he’ll actually be around when baby is here but idk. I recently got a job opportunity in another state. I decided to take it. It’s 18 hours of a drive away from where I’m currently living. I told him this and he was visibly upset. In my defense I’d be much closer to family in that new state. I’d rather have a solid support system then an inconsistent one. I told him he’s welcome to take his 3 months of paternal leave and be with baby when she’s here. He’d just have to okay it with his gf. Honestly part of me took it because I needed to get away from him and his gf. I’m still so heartbroken. This is the worse heartbreak of my life. I feel like in order to heal and be the best version for my Baby girl I need to start over somewhere new. I can’t do that here. I hate seeing them together. It hurts me every single time. But I can’t say that. I’m trying to be civil for my Baby. She deserves to know her father. Any words of confirmation or advice would be highly appreciated. I’m so scared I’m going to mess up this baby
