The other day I noticed on my boyfriends Instagram that he started following a random woman. I asked him who it was and he told me it was none of my business. I later found out(not from him) that it was a friend of his friends girlfriend. Apparently the friend and his girlfriend were with my boyfriend. This girl called by video and they were all having a conversation together. She then added my boyfriend on Instagram and he started liking her photos. I asked him why he felt the need to follow her and start liking her photos when he doesn’t even know her and he got really angry, called me jealous and broke up with me!! Saying he can’t tolerate jealous behavior. We have had several instances in the past where he did similar things and we fought about them but got over it. Now I’m thinking he has started talking to this girl through Instagram and that’s why he ended our relationship. This girl doesn’t even live in this country, she lives abroad. So the chances of a relationship with her are slim. Why would he do this? I’m very upset and want him back? Am I being stupid and should I just let him go?
