Feeling abandoned

My partner just left me, on the floor, crying my eyes out while trying to calm down 2 small babies. I had an abortion consultation over the phone barely an hour ago and he was being super unhelpful before hand and had an attitude with me. When i finished the call he literally just upped and left because i told him if he was just going to make a shit situation even worse he should go. I've never felt lower in my life. He promised he'd be supportive and helpful with the kids. And yes, this is what he wanted, with our second daughter (born just under 3 months ago) he kept pushing me to abort and threatened to leave me if i didn't. So yes, he's very on board with the abortion. He just hates when i have emotions and expect him to a decent human being. He's never been a great boyfriend but this is just a new low 😭 I've never wanted to break up as much as i do right now. What kind of a person does that?!
