I know it's not my place to decide, so I'm just getting some advice here.
My fiance has already decided who his groomsmen will be, but he hasn't asked any of them yet. (Engaged 2/11, wedding 11/6) He is waiting because he can't decide who will be his best man, and wants to decide before he asks anyone... So on to the advice part.
Two groomsmen are his brothers - J is same age, B is about 5 years older. He's always been close to the same-age brother, but has gotten really close to the older brother in the last few years. I('m a little nervous about picking one and hurting the other one's feelings.)
One groomsman, C, has been his very close friend since at least middle school, and he even lived with him for a year or so during high school.
One groomsman, M, he has been friends with since high school (so ~10 years), and lived with for a year or so during college... still good friends, but we live several hours away from him, so they've drifted apart somewhat...
The last groomsman, G, he has been friends with for 5 or so years. They were roommates for most of college, and they are probably closest of the three friends.
Any thoughts on the issue??
