I have a friend (more like a closer acquaintance), frankly I don't like him that much. Anyway he has a boyfriend who I have never seen. I just know he has one. Anyway I run into some guy, talked for a bit, went out once, and I noticed that as I was returning to "his"place it was oddly in the same area as my friends, further travel divulged that it was also on the same floor, a quick right turn and it's the apartment. Anyway I give an odd look and say "I'm going to go." and leave.
I am sure that was odd as hell but I have no problems with being short.
I am wondering if I should tell my "friend" that his boyfriend is seeing people while he's not present. Most likely seeing more like, as if he's willing do see me there could be others.
