Just need a little advice.

Me and my boyfriend finished over a week ago now and a day later I found out I was pregnant. I already have two children who are only still very young. I wasn’t too sure what to do. We broke up because he didn’t feel like he could take my children on, I never expected him to play daddy but anyway I’m still very hurt over it as we were together nearly two years. He doesn’t want this baby at all and I was in two minds. But now I’m moving towards abortion as Much as it hurts me to say it it’s probably for the best. He still loves me and all the feelings are there but feels that it’s right we’re not together. So I’m trying to deal with that and the idea of getting an abortion. He said he’ll come with me and be there for me. I’m upset that I have to do this so please don’t judge me. My son has a medical condition as well so would be even harder with another child to look after which I would be doing alone. I don’t really know what my question is I just feel like I need to tell someone as I have no one to talk to. How can I deal with this? Is this something I’ll always think about? My ex says it’ll be easier to get over than having the baby that won’t have him around all the time. I’m going to the doctors tomorrow to talk about it. I want my ex back so much, he was such a nice person 😔 I’m just feeling really horrible about it all 😔😔
