Parent or Abort

So I'm currently pregnant and a single mother of 2 babes! Both Fathers are in their lives so that's great. But I'm also pregnant again with my youngest baby's father. He was super upset the first time around and here we are again not even a year later.. I mean how it happened again is obvious, how we tried to stop it doesn't matter.. Either way here we are AGAIN! He is for the ab and I'm on the fence. I don't really feel happy about it. But I'm scared and do not want to have an ab. I feel that if I do this I'll be the girl who cries every night because of what I did and could have been just an emotional ball of regret.. and I can't be like that when I have two kids to live for already. But do I really have what it takes to take care of 3 children most of the time? Will the dad come around for this baby and we can work as a team and become stronger. I just don't know. He seems very strong about his feelings and he'll hate me for probably the whole pregnancy like the first time. He was such a shitty person, but now he's always there for his child and me to be honest. And I feel like this will just ruin it all at least for me and him. But as I write this I just feel like I'm being selfish now. Abort the baby to keep me and him civil and suffer from the ab mentally for the rest of my living days. I'm hurt and upset I'm here again.. either way a decision will be made. I just needed to vent my frustration. Some of you might disagree some of you may not understand some of you have "all the answers" and some may support either way thanks for letting me clear it off my chest.
