Boyfriend pushing abortion

So I really think I may be pregnant because my boyfriend came inside me unprotected a couple weeks ago & I had a little spotting today. I told him I was bleeding & I said I think it's bad if I am pregnant (even though I'd love to be) because I've been drinking alcohol/smoking frequently lately. My exact words were "I would feel so bad for this baby if I really am pregnant" & he said "you don't have to worry about it because that baby would not be walking on this earth" (he's implying I would just be getting an abortion) he said it in a joking way but he really doesn't want to have a child. I don't know how to feel about this....any thoughts? please comment.
