My bfs bestfriend since they were in the 4th grade is getting married. He called him the same day he proposed asking my bf if he would be a groomsman bc he picked his fiancees brother to be his best man. He also asked my bf if he would plan the bachelor party.... now, he hid this relationship from his best friend for 3 yrs and everytime we hung out with him he complained about his future brother in law. Does my bf have a right to be upset? We are thinking his fiancee made this decision. Hes only known this guy for 5 yrs.
