Yes, I know this is a petty drawn out rant, but I'm about to lose my shit. My fiance's family is making this wedding into a giant circus and a nightmare. His mom invited a bunch of her family and friends against my wishes, but she is paying for a chunk of the wedding, so I figured "just suck up your anxiety for one day". Nothing says wedding day like an anxiety attack. Now, we find out half the people she invited aren't even coming....after we signed the contract with a guaranteed minimum. They waited until yesterday to start telling us this, so it is cutting it way too close to even fill the seats and we have to just eat the cost....over 2k. Then it was all the special dietary needs. I mean, I get that there will be allergies and I want to accommodate everyone as much as possible, but seriously?? His mom is "gluten free", his brother and wife are vegan (totally don't have an issue catering to that since she agreed to take a bridesmaids place last minute), his other brothers wife is pregnant and apparently now only eats chicken fingers, so we're paying over 100 dollars for her to eat chicken fingers...Ok, cool, got over all those hurdles and yesterday was our final walk through. Got everyone's special dietary needs settled, processional order figured out, seating arrangements, all good in the hood. On the way home, it occurred to me that my fiance had his pregnant sister in law sitting on my side for the ceremony. Not the reception, just ceremony. I wanted to give her a heads up so the day of, everyone can find their seats quickly. The idea stemmed from the fact that I have no family coming and since she has 2 kids, we could have all the cousins sitting together and it wouldn't be a fight to have my son sit down since he knows them and isn't shy towards them. She throws the biggest fit fighting with me. It's ten minutes out of one fucking day and you can't just sit with my kids so I can have my kids on my side? So that the photographer can take one shot of the kids and be done? So we can get the ceremony over with and my son isnt spending 5 minutes with shyness refusing to sit down? I have changed so many things to make sure this family is comfortable for one day. For MY wedding day. This was my breaking point. I told her that I'm passing the torch to my fiance and she can take it up with him because I don't even give a shit if we just cut our losses and elope. I then told him that her and the kids are sitting on my side so that my son is comfortable and the photographer can take a "kids" shot or it will be direct blood family and bridal party only at the ceremony and she can sit her pregnant ass inside until it's over. It is for 10 minutes. Yall can't talk during. Get over it. 🖕
