Overheard boyfriend

I just had a baby two weeks ago. I just heard my boyfriend who is my newborns dad tell his gaming friends that I had one more week before he would start expecting sex from me. And if I couldn’t meet his demand that he would find someone who was willing and ready. I confronted him right there and he tried to make it seem like he was just joking with the guys. Like wtf dude, I just had your baby.
