Arggg it's tough to be the child of divorced parents and always walking on egg shells not wanting to upset anyone.
I got married at the grand age of 42, bless my parents, they were really excited! Planning was all going well, but arranging the top table almost reduced me to tears. In between the best man who decided without consideration that his wife should be at the table, then the issue with my parents and only a total of 10, it was a real headache!
I made the first booh booh because I thought that maybe, my mum would have wanted to seat next to some friends she had a business interest in common and she had stated that she was looking forward to be able to meet them to discuss it. When I mentioned it, thinking I was being mindful of her needs, she went berserk and took it I wanted to exclude her from the table. So instead, I asked that she be seated next to me with my dad with his wife further away because my dad had the 'honour' to walk me down the aisle.
Except that this request had been missed and my dad and SM were seating next to me, with my sister and mum at the end. It was clear when I walked in that my mum was furious, which led her to make some snappy comments when my dad made his speech. It went from bad to worse and my mum ended up leaving for the hotel early.
It certainly didn't ruin my wedding but it did put me under pressure as I was upset that my mum was upset and had assumed I had intended to push her away.
So please please, let it go. If you love your daughter respect the fact that it is all very awkward for her and she is only trying to please everyone.
