So, I've got 2 definite yes bridesmaids/men, and my other half has 2 definite yes groomsmen.
I did have three bridesmaids (two men (D & G), one woman (C), but I found out this morning that the other half asked D to be his groomsman. Long story short, we've both been friends with this guy for YEARS and he's basically family.
Anyhoo, we asked him whose party he wants to be in (as long as he's there, I'm a happy bunny), and his reaction was thus - "BOTH!"
So, I'm just wondering if there are any bridal-party-neutral roles (aside from ushers, we don't need those

)!
Re: Alternative roles?
Wedding party

And (if you are having a Catholic ceremony) a person to present the gifts.
Personally I think asking someone to just be an usher is more of a job then an honorable position.
But seeing as your FI already asked this guy to be on his side and the guy said yes, then I would just keep things the way they are.
I guess what I'm saying, he can still support you even though he is on a different "side" then you. I guess I don't see the need for an alternative roll for him.
We have one guy who we couldn't choose between. He has the personality to officiate (outgoing, good public speaker, etc.), so we asked him to officiate. Maybe you can do the same, OP.
I guess I'm in the camp of whether he's standing up with you or your FI then he's standing up for you both, side shmide.
Other than officiant as others have suggested there's nothing to say you HAVE to have 'hers' and 'his' parties, you could just have a wedding party if you'd prefer. They don't have to have special titles, just the knowledge that they are your nearest and dearest and you want them by your side on the day.
lyndausvi said: This is true, I guess! I mean. he'd be on both our "sides", I was just wondering if there was any title for that! (my question was badly worded)
We're about as far from Catholic as you can get! I think we might ask him to do a reading
But are you going to keep him as a GM? Since your FI already asked him to be a GM you really can't renege that offer. But he can certainly be a GM and do a reading as well.
Yep, I missed this part from the initial post - if your FI has already asked him to be a groomsman you should probably just leave him be. Since you obviously had the conversation with him it sounds like he knows you would have been happy to have him on either side.
