For the day of the wedding I'm having a hair and makeup artist come to the venue for me, my mom, my bridesmaids and possibly my grandma if she's interested. I don't particularly want to invite my FMIL or FSIL. I don't have a great relationship with FMIL, its cordial at best and cold and contentious at worst. SIL and I are on fine terms, but she tends to start a lot of drama and can be unkind and inconsiderate (ex: I invited her to be a bridesmaid, she said yes and then had a meltdown while trying on dresses and dropped out of the party).
I would prefer to just be around people I love and am comfortable around, because I know I'll be nervous and emotional to begin with. Is it incredibly rude to not include them?
Side note, I'm paying for everyone's hair and the makeup is optional, the girls are paying for that if they want it. I know neither of them would want their hair done so money isn't a factor.
