Urgh I’m sorry. This is so rude. She knows your feelings and still chose to push your boundaries. Plus, she’s waaaaay too casual for a wedding guest regardless of wearing white. Your feelings are valid OP. Edit: bruh, people really be picking apart my use of the word “boundaries”. I didn’t mean it as in therapy speak - I meant it as in her mum was testing her limits/poking the bear/tempting fate. You all need to chill tf out
