I have a problem with my boyfriends friend.. Help please!?

Awhh you must be so annoyed! i hate people like that.. try to break people up! I know you trust your b/f and he sounds really nice but could you like say to him how she is annoying you and he sounds very understanding. He will probably tell you there is nothing going on and nothing to worry about and feel sorry for you since you feel so sad. He will spend less time with her because he obviously doesn't like her as much as you. Everything will be fine :) I hope everything goes well and that i helped. Just tell him how you feel when you read the messages and he will understand :) xx
