Weird that it bothers me that my boyfriend is close to his sister
So it mainly started bothering me one day when I went over to his house to visit him and his family. I went back into the gaming room with my boyfriend and his sister and they started telling funny stories about experiences they had together, and it bothered me. I felt upset that she seemed to know him better than me. They seemed so close and it upset me. I want to know him like no one else and I'm so upset she knows him better. Is this normal?
