My fiance and I are paying for our wedding completely out of pocket. We chose a small venue that can only accommodate 100 people. As such, we have to be very frugal when it comes to the guest list, and, bad as it may seem, the "plus 1" option was the first to go; we both come from large families and it's been a nightmare enough to cut it down to 100 people (we're still stuck at about 140 already).
FI has twin cousins that are 21 or 22. One of the cousins ("brother A") has been with the same girl for 6 years and she's basically a part of the family and has become good friends with FI and I. We planned on inviting her, but not as his plus one, but as a separate invite; she'll get her own addressed to only her and sent to her own house. The other brother (brother "B") was in a relationship for about 2 years and we were planning on the same since that girl and I had become close friends.
However, brother "B" and his girlfriend broke up about a month ago and I just found out that he just started dating a 17 yr old that he just met over the summer. Are we obligated to invite her now since we are inviting the SO of brother "A" or are we covered by our overall "no plus one" thing?
I know this is treading thin water.
