How would you react *update*

How would you react if your boyfriend told you if you got pregnant, he would want you to get an abortion and if you didn't then he might leave?

This conversation got brought up last night between us. I'm on birth control but he accidentally came in me a little bit yesterday (1 day after i ended my period). Now i know the chances are very low and im probably not pregnant but out of the blue he said "if you're pregnant, you're getting an abortion.. right?" And i didn't say anything because i never saw myself as one to get an abortion. So we talked about it more and i said well what if i wanted to keep it? And he said depending on the situation he might leave because he wouldnt agree with bringing a baby into the circumstances we have (aren't married, don't have stable jobs/careers yet, he's 21 I'm 20, etc).

Now I'm really heart broken and can't stop thinking about what he said. I just never expected him to say something like that.

*UPDATE*

i texted him telling him i thought it would be a good idea to stop having sex for a while and he freaked out. I told him what he said had been bothering me and if he was going to leave me if i decided to keep a baby then I'd rather just stop having sex and not take the risk of getting pregnant and losing him altogether.

He said he only told me he might leave because he was mad about me saying no to abortion and he apologized saying he didnt mean it. I really dont think im pregnant right now so i wont take plan b, but i think i will tell him to use a condom along with my birth control from now on.
