Can I go ahead and say my s/o's maid of honor is a victim playing selfish person and that she was crazy?
What has the maid of honor done to you?
She's been trying to ruin my wedding for no reason.
You'll need more evidence than just your word for that one. You'll have to be respectful to her since it would bother your SO.
I'm not cleaning up after her after the wedding so I don't care.
I know weddings are super stressful for everyone, but I believe it would be fair to just let her be. Perhaps try to ask her and your SO if they're having trouble with anything? They would appreciate the respect and concern, and clearing it up can bring a happier wedding.
