I'm think about abortion.?

I just found out I am pregnat. I have a 2 year old with my soon to be ex husband, we are going through a divorce. I am contimpating abortion because I raised my first child all on my own finacially and it was hard. My husband did not help me at all. I just feel like I'm going to be a baby killer. My husband is a dead beat always in and out of jail and I found drugs in his car so I filed for divorce finally. We used condoms the last time we had sex but the condom broke but i did take the morning after pill. I just don't know what to do. It's already hard as it is with one baby and his drama and I can't imagine a second one. Am I wrong for thinking about abortion? What would you do?
