Casual sex partner ok with unplanned pregnancy???

Long story short; my period was late and because I consume alcohol very regularly, if I’m even a day late, I test. My sexual partner, who I’m not dating, got pissed I didn’t tell him I thought I might be pregnant (because I didn’t think I was) and then made comments about how if I did get pregnant it would be fine and we’d handle it.

Sign of a mature adult who understands sex makes babies, or a little concerning given we arent even dating? I feel like he’s trying to get me pregnant or something after those comments lol.
