So I’ve been dating my boyfriend for a year now and we are very serious. He is extremely jealous whenever guys talk to me so usually when a guy will try talking to me on faceook or something I’ll just tell them that my boyfriend wouldn’t appreciate my talking to them and they leave me alone. But recently his very bestfriend has been messaging me on facebook my boyfriend was aware of this and he was okay with it. At first it was friendly but then he started very obviously trying to flirt with me. I didn’t respond to any of his advances and eventually he got the hint and stopped trying. My boyfriend always wants to know whenever another guy is interested in me and he usually ends up confronting them. I don’t want to turn him against his best friend, but I also don’t like the idea of keeping anything from him. What should I do? Should I tell him about it, or just let it be?
