Stupid asss

So my bf and I literally spend everyday together and it’s cute and whatever but to a certain point . So the one night I didn’t go over his house he told me he was going to a club and bar or whatever . Which was fine we’re not married or have kids together . Go out , enjoy yourself . Soooo the next day mid afternoon i go over his house and him and his friends are just like boasting about how much fun they had and how many strippers and girls were on him (my bf) and I’m just thinking like why talk about this in front of me . Y’all had all morning and early afternoon to talk but the moment i get here , it’s a top story . And it’s not like they were talking to me but came in the room where i was to make sure i hear it. Like would i be rude if i just leave ?!?
