Bat, I hear you defending H a lot even though he's treating you poorly. I see you accepting this poor treatment but it's still HIS fault that he's behaving this way. He's the one making these hurtful choices. I don't think it was manipulative of you to ask him whether he will come back.
Just because he says he isn't happy, or even "heartbroken," doesn't mean he can just do whatever he wants. You are in a relationship and your needs matter too, Bat. I still think he's being manipulative. And he's gaslighting you because he's trying to normalize his cheating and possibly even have a child (!!!!!) with OW. The idea of using OW as a baby-maker so he can have a mixed-race child is so messed in so many ways. It's also delusional that he thinks having a child in this way would somehow earn him the respect of others. Bat, why do you want to be with a person who treats women like this?
