What if your boyfriends brother likes you?

Answer 1

Be polite but try not to spend time with alone with him or flirt with him. Change the topic of conversation or make your excuses to leave if he attempts to flirt with you. Like most crushes, he will get over it in time if you don't show an interest in him.

You didn't mention if you are interested in him or not, but there will be major consequences if you go after your boyfriend's brother. There is no good ending with this type of situation. You will be responsible for causing animosity and tension between the two brothers, feelings that would spill over into whatever relationship you could possibly have with the brother. There also would be tension with the rest of family as well; it seems like an uncomfortable scenario to put yourself through for a relationship that most likely would not work long term.
