i’m (25F) and confused what did he (30M) mean by this??

TL;DR Hello we’ve been together for a few weeks and i was talking to my s/o about sex because he was saying he wants too much and i’ve always been scared of getting pregnant and he said “just take the damn pill” then i said if i got pregnant i would probably end it all because that’s my biggest fear and he hit me with “i mean it’s like I’d leave or some shit but damn it’s too early to think about these things” I’m extremely confused did he meant he would leave if that happened or??

then after a while he said “leaving a girl just because she’s pregnant is so dirty” now i’m extremely confused??
