A bit of background info: my boyfriend and I are both 20, have been together since we were 16. I am his girlfriend, kiss, etc. He is my first serious relationship. We go to different universities and are currently LD (even though it's summer, he is in a co-op program where he works for 4 months and then goes to school for 4 months and right now he is at school while I am home for the summer).
Yesterday he went to go watch a badminton tournament at a club near his university, a lot of his friends were playing, including his best girl friend, Kate, and best guy friend, Ian. One of his other friends, Dan (who is on his work term right now, and not at school with them) drove down to play in the tournament but it ran later than expected and ended at 12:30am. The 4 of them (boyfriend, Kate, Ian and Dan) went out to eat afterwards since the tournament started at 5pm and they had not eaten since then and it was late by that time so Dan decided not to drive back and crash at a hotel. My boyfriend, Kate and Ian decided to stay with him so he wouldn't have to pay so much for the hotel (none of them had a couch/spare bed to offer him) and the only room available was a room with 2 queen beds.
Dan has a stomach problem..very gassy guy and so nobody wanted to sleep on the same bed as him. They drew straws and Ian lost so my boyfriend slept in the same bed as Kate. They are best friends and I trust him that nothing happened etc because he really sees her as a guy, he calls her "dude" and I've met her and seen them interact. Conversations between them are always scattered with "man/bro/dude" etc. Plus it was a queen bed so it's not like they were forced to cuddle up.
My boyfriend told me all of this today when he got back home and my first reaction was "whaaa" because we'd always said sleeping with someone of the opposite sex that wasn't your SO was kinda weird but then I thought about it and since it was Kate, it was no big deal. But then I thought MORE about it..and I thought to myself that if it was me in that situation, I definitely would've taken the bed with the girl rather than share a bed with a guy (even if he was my best friend and we were purely platonic).
Now I feel like my boyfriend doesn't "respect" our relationship as I do, I think his thought process is that he knows that his intentions are pure so it's fine. It's not so much that he shared a bed with Kate that bothers me as the fact that he didn't consider that he has a girlfriend. Am I overreacting?
Apologies for the length!
