I'm getting married next Sunday. We're having a small wedding with just close family and friends. For context, I am not even inviting my own cousins even though I'm close to a lot of them, because they live abroad and we wanted to keep numbers down.
My MIL lives in another country with her partner who has two DC from a previous marriage. The DC weren't invited, as my DP doesn't feel close to them at all (his DM and her partner got together when all the DC were adults). We sent out save the dates about a year in advance to all the people we wanted to invite, and informed MIL and partner that we were not inviting the DC. They seemed fine with it.
Anyway, about 5 months ago, before we had sent official invitations, MIL texted DP with a picture of her flight confirmation showing that she, her partner AND DC2 had all booked flights for the wedding! We were obviously pissed off because we had told them we weren't intending to invite DC2, but let it slide because there was bugger all we could do at that point. When we sent out invitations, we included DC2's name just to be nice.
Fast forward to now, 1.5 WEEKS UNTIL THE WEDDING, and DC1 has now 'confirmed attendance'!!! DP and I are utterly incredulous but we can't say anything because we need to keep the peace for the sake of a drama free wedding.
Call me crazy, but surely you can't confirm attendance to SOMETHING YOU HAVEN'T BEEN INVITED TO???
