Why me!!

So I recently found out I was pregnant. I told my husband and he flipped like it was all my fault or something. Long story short he told me to either get an abortion or we will get a divorce. We have two kids already (one being his) ages 1 & 3. I have no clue what to do. I had an abortion when I was 18 (not by him) already and regret every second of it. I can't imagine myself doing it again but it's also my marriage and family being together at the end of the day. What should I do?! I'm completely hurt by him giving me those two opinions and can't even understand who he is right now! I'm emotionally stressed and just want to make the absolute right decision. Anyone have any advice? I told him I'd have to think about it. My mind is kinda made up but I want to hear others opinions. 😭😭 Also what if him and I don't make it after the abortion if that was to happen?
