Would you have your child around someone who disrespects you??

So I am pregnant by twins by someone I have a 5 month old child with.. both times he urged and abortion but I didn’t go through with it because I am anti abortion and got stuck when it came time.. anyways, he stayed with me my first pregnant for the first 3-4 months and then we split.. now with the twins I am 12.5 weeks and once again he’s urging me to get an abortion. Both times he stayed with me and this time now he’s talking about moving out since I won’t get it.. he’s been bashing me and calling me names and admitting to only living with me because I was the cheapest person he could stay with (talking about the other women he talks to), he’s said he regrets ever living with me, and said that he wishes he never came to stay here.. he’s going through a bad time and lost his place to stay so I’ve been letting him live with me since before I got pregnant with my 5 months old.. I’ve known him at little over a year before I had our first child so this all new to me with the way he is reacting... would you let somebody that disrespected/disrespects you come around you child??

Like the last pregnancy he didn’t go to any appointments, gender reveal, or anything and told me the whole pregnancy “what am I supporting if the baby isn’t here” my whole pregnancy since I was considered high risk and kept asking for his support. So I’m sure he will do the same to me again. We’ve literally been doing good up until today where I told him I wasn’t getting it done because it makes me very uncomfortable.. what should I do?
