I was going to post this in AIBU but I am being a whimp. My BF and I have had a rocky relationship, and broke up for a month around Christmas, consequently he moved out of my house and into a house share. Since getting back together things have been going really well and we are in a really good place so I really don't want to cause a mountain out of a molehill.
Last night my BF was given a last minute opportunity to go away for a few days by his male housemate, he leaves tomorrow. It transpires that this trip also includes his two female housemates.
AIBU to find this unsettling and to be honest a bit inappropriate, I'm not sure why I feel this way it just makes me so uncomfortable. He thinks he is doing nothing wrong and am being "mental". I don't even know why I feel so unhappy about this but it really bothers me.
