Opinions?

When I found out I was pregnant, me and the baby's father broke up.. things just wasn't working and I don't have feelings for him, there is no love there. We were literally together a couple of weeks. However, I am considering getting back into a relationship with my ex who I do love and always have done. She has offered to pretty much be a second mother to my baby and give me all the support I need (would be a lesbian relationship) she makes me truly happy and I want her in my life and my babys but I'm worried about so many things. My parents/family don't like her due to them being anti-gay and I'm not sure how the babys father and his family will react when he finds out I'm with someone else. He wants everything to do with the baby, but also wants a relationship with me after me telling him so many times I don't want it. I've never once denied him access to his child. It seems like all he cares about is a relationship between us. I am willing to be civil with him for the sake of our baby. How would birth work? I want my partner there to support me obviously, but If she was there my family wouldn't want to be there and I know the babys father would fight to be there for the childs birth but truth is, I really don't want him involved in the child's life because he's unreliable, immature and I feel he would just make things worse but I have to obviously give him that chance for my baby 😒
