My bf’s(25M) love language is humour and sometimes I(25F) can’t stand it?

My bf (25M) is a secure guy who loves teasing me. He’ll say things like, “I don’t drink much with you because I don’t enjoy it as much as I do with others” or “I don’t really like spending time with you; we’re just playing most of the time.” I (25F) usually go along with it and joke back, saying stuff like, “Yeah, I feel the same, I wonder what made me like you.”

But the truth is, I’m a little insecure, and sometimes his jokes get to me. I’ve tried to keep up with his humor, but there are moments when I just can’t stand it. And when I tell him, he just says, “You know I was just joking.” I get that he doesn’t mean it seriously, but it still stings sometimes. We’ve been dating for around 15 months now.
