So I've been been with my boyfriend for almost a year but I noticed that he started hanging out with a group of girls. One of the girls is one he used to like. At first I asked him what was up but he said nothing. After awhile i noticed that he hung out with a different girl in particular, if we are in class and he walks in, the first person he goes to is her.....then me. There was even a point where I wouldn't be able to find him and when I did, he'd be with them. I've tried not thinking anything about it but he just makes me wonder. I also think that the feelings are mutual because she always looks for him and today I was talking to a friend and I mentioned his name, she turned her head so fast, I could have sworn she got whiplash. I don't want to take his friends away from him but at the same time I want to know what the hell is up.
