Im confused 😖

Amour • ttc my first baby, I can`t wait to be a mother
Me and this guy I'm friends with, well friends with benefits with we had sex yesterday and he used a condom but it broke while we were doing it then after he just took it off. He talks about wanting another baby because his daughter is 6 but I asked him if he came and he said no after all that. Im wondering What if he did c*m and didn't tell me. It's not a problem because we both agreed on the baby but idk I'm just wondering
