So, invitations have been out since September 3rd. The last day to RSVP is October 3. Counts are due to the caterer by October 7.We have been very clear with my mom that the venue will only hold 75 people - we are not counting kids under 5 in this total.As of right now we are up to 63 confirmed attendees with another potential 30 outstanding (of those we epxect about 15).Last night my mom calls me and says "I want you to invite your aunt and uncle xxxx." We had already discussed this extensively before the invites went out. Cousins XXXX didn't invite me to their weddings, my dad had a failed business relationship with uncle xxxx and they haven't gotten along since. We already agreed on this. I like my cousins, but there is a limited amount of space.So my mom says "well, I'd like to send them an invitation." Actually, I'd like to as well. One of my cousins enlisted their help for a killer bridal shower, but it was with the knowledge that there might not be space for everyone. I know that's a bit awkward, but it's a small venue. I adore my cousins and I'm happy to be back in touch with them after all these years.The question is - how do I handle my mom? I honestly do not have the time or emotional energy to deal with this. I don't even have time to be writing this down except that it's bugging the crap out of me. I suggested to her that if she wants to invite them, she call them and tell them. I don't have time to re-do the RSVP cards with a different date. Of course, she didn't want to call them because she hasn't talked to them (except at my bridal shower) for over 15 years.Anyone? I think I'm going to insist that she call them. Tell them that some space has opened up (5 of her family members already negatively RSVP'd) and she'd like them to come. Any other ideas?
