Don’t want to invite groomsman’s girlfriend

Duplicate post

You must mean attention. Unless she's the type to cause a major scene, if they are a social unit, she needs to be invited. Being jealous is her problem, not yours. If you think she likely to cause an actual disruption then FI should have thought about that before asking his friend to be in the wedding party or inviting him at all for that matter. Dating a person who has issues that rise to that level comes with consequences.

If it's more that you really just don't like her, chances are you will too busy to even notice. But yes, barring something really extreme, you need to invite her.

Yes. I'm not getting the sense she's a threat of any kind, only that you don't much like her.

Yes you need to invite her. You can't expect your GM to come celebrate your relationship while you're disrespecting his.

You can ask someone to kind watch the vibe and if it seems like things are heading in a negative direction, redirect it. Not really babysit the guest, but kind of monitor and make sure you guys don't have to worry about it. We actually have our ushers doing this so we can focus on enjoying the day. I am also a little more direct and don't deal well with such situations so I have given them permission to redirect once and if that doesn't work they ask the guest to leave.
