<human>: So, I trust my gf wont cheat or anything but I just dont like the idea of her grabbing somebody tight and people mistaking them being together and whatnot. I told her I dont really like it and she continues to do it. However, its with a guy that is 6 years older than her, and he's married, but he has cheated before. Shes known him for a long time and says hes like an older brother to her. They became friends by her sister being friends with him at a young age, and her sister and him have always been close friends. So, do you think im making something out of nothing? The part that mostly bothers e is that i told her I dont like it, and she continues to do it.
