Pregnant... Boyfriend wants to keep..

Boyfriend and I have been on and off for a year or so. Recently I finally left him for good. Found someone new. Then I found out I was pregnant. It can only be his, so I told him, and I had thought already about abortion because the timing is just so off.... But if I do this will it hurt him? I have no clue what to do. I'm 17 and really don't need a kid, I have so much going on already. But can I morally live with myself if I get an abortion....
