merd I do the exact same thing, I always get email confirmation and keep it as a record of what's agreed/discussed I don't trust people not to twist things.
My wedding was epic in terms of DM and DGM misbehaving! I hate attention and wanted to have the least amount of fuss as possible sooooo obviously DM went out of her way to do the opposite.
Tried to cause problems with my dad by getting me to uninvite him and SM.
Party the night before that didn't finish until midnight when I had to be up at 6 am, made food for everyone there but didn't cater for my food allergies or tell me she wasn't so I had a tiny turkey roll all night
Invited the whole family and her friends to leave from her house with me the morning of the wedding even when I'd repeatedly told her no.
The morning of the wedding she woke me up 30 minutes before my alarm by walking in switching on the light and telling me to "get up" my 2 bridesmaids got tea in bed and one of them woke up with her stroking her face 
Then she refused to help me get dressed just got herself ready and sulked, cried in the car on the way to the ceremony because I didn't tell her she looked nice in her outfit?! She didn't tell me I looked nice either...
sulked all day and hardly spoke to me apart from for pictures!
She also told everyone I was acting like a total bridezilla, we had a religious blessing for dh after our civil ceremony and while I was getting changed she was telling everyone I was goingto call it off because I was going ape shit, dh ran up to the hotel room to find me calmly but firmly asking people to start moving down stairs so we could start the blessing as we were over running by an hour on timings for the day. My aunt still says about me being all bridezilla as if it's a joke makes me want to cry, god knows what our friends think of me 
Then the morning after she had a huge meltdown in the car park of the hotel in front of half our guests about how hard she'd being trying but I was a horrible horrible person who had been unbareable then drop off leaving me, dh, 2 bridesmaids our puppy with all our luggage and our wedding outfits to get home in a Toyota yaris 
When we finally got back to her house she refused to speak to me spent 2 hours telling dh and bridesmaids what an ungrateful spiteful bitch of a daughter I am and had barely spoken to me since that was 2 1/2 years ago although she spends all her time telling people she doesn't know what she's done and why I refuse to speak to her?!
I spent the week after my wedding in tears poor dh wedding and honeymoon was ruined as I still can't look at the photos and have very few happy memories of the day 
I've probably outed myself there but I'm preparing for nuclear fall out of us maintaining NC after SF's call this weekend so I'm a bit meh about the whole thing!
Sorry for the essay/rant! I feel better now though!
Is it time for afternoon tea?
