text: Okay, this best friend of his is extremely out of line, not to mention hes immature. Don't take him or his actions personally. However, if "the best friends" actions are making your boyfriend act differently to you, then you need to be having this conversation with your boyfriend-Right Away.\nIf your boyfriend is influenced by his best friends immaturity, something is indeed wrong. I would second guess your relationship with Him.\nHowever, give you boyfriend the chance to explain why he is acting out like this. Then you decide what is best for you to do!
