AIO? My boyfriends friend has a problem with me asking him not to sleep in a bed with another woman.

Hi everyone, my boyfriend has a big group of friends with lots of girls in it. A lot of times after they go out or have too much to drink, they’ll crash at someone’s house. One night he came home and shared he slept in a bed with this girl (who the texts are from). We did not have a fight at all – I know he’s grown up doing this. I told him I wasn’t super comfortable with that and asked if he could not do that, to which he did not argue at all and expressed total respect for my boundary. We have not spoken about it since.

She texted me the morning after they went out, which are these pictures. Am I overreacting by telling her she’s overstepping or are her concerns valid?
