My family won't use my pronouns and it hurts every time

I've explained it calmly, sent articles, corrected them gently, corrected them firmly. My mom still introduces me with the wrong pronouns at family gatherings. She says she loves me and she's trying, but 'trying' for two years looks a lot like not trying from where I sit. Every misgendering feels like a small rejection. I don't want to cut them off, but I also can't keep absorbing this. How do you cope when family won't get it right?
