My bf of Almost 2yrs told me this.. how should I handle it???

He got home from work last night, got ready for bed & was drinking a beer to bed. He was ranting about 2 of his coworkers getting fired.

Then he mentions his small group of coworkers that work near him. (in their early 20’s) About how they obsess over a female there, but she has a family already & he thinks it’s childish. Then he brings up another female they obsess over. (she’s married) & I said “you should’ve gotten with her” (just because a long time ago she used to like him & he brings her up occasionally for example: she dyed her hair blonde+ I feel like his coworkers influenced him to behave like that) & without hesitation he said “I should’ve, I would’ve had like 3 kids already”..

Not sure what was in that beer, because he didn’t recognize saying that. Since he was clueless as to why I told him to sleep in the other room..

When I said it about other coworkers he quickly rejects it, but this time he didn’t.
