NTA; It’s not only her wedding, you are getting married to each other it is an important event in both of your lives, not only hers. It feels like your feeling are not taken into account, your mother is your only family–and fuck man, being that I’m close to losing mine to cancer-- nothing could convince me not to bring my only member of family to my wedding, after all itisyour wedding too.

A wedding day is important but I could never take that away from my mother, dementia or not, firecracker or not. This is a good hill to die on.
