Groomsmen Discussion

Ask him to stand on your side. I’m honestly of the opinion that each person should be able to choose who they want to stand by them based on the relationships they have individually.

We both agreed do have one from each side of the family to symbolize the unification of both families. It’s a tradition in my family. Maybe tell
Him you want to start in it yours. I don’t think it’s a big deal you can tell him he doesn’t have to participate in any of the activities he’s just there in the day and for the pictures. That’s the middle ground we met on.

Have him stand on your side. I agree with your fiance; he is not close to your BIL and is not obligated to ask him just because BIL is your family. If you really want him to stand up in the wedding, have him be a bridesman. He can still wear a suit, but will simply stand on your side during the ceremony. It's becoming very common for people, regardless of sex, to stand up next to the person they're closest to (rightfully so!).

My husband didn’t want my brother on his side so I made him a bridesman.

I don’t think it’s wrong your fh doesn’t want someone on his side that he’s not close to. You could as pp said have him on your side or have him walk in the professional or have him be an usher

I don't think you should make him be a groomsman, it's more for people your FH is close with. There's other jobs he can do like give a reading or be an usher

I don't think he should, if they are not closest of friends outside of groom's relationship with you. You pick your people, groom picks his. If he wants to be an usher, not one of the groomsmen, and held seat people, and escort Mom's and grandmother's too, for that he need not match anyone else in his suit. Ushers are often family .
Or he can be your bridesman. But it is not right to push someone you want on Groom, or for him to do that to you. It usually causes problems, sometimes long lasting bad feeling.

I don't think your FH should be obligated. His groomsmen are standing there because they played an important role in his life. Have your BIL be an usher. That way he matches the wedding party and is in the photos.

Have him on your side. He can be a bridesman which is pretty common.
