I hear you too! Families can be crazy.
My Mom's family is being assey too. They never called her or wanted to visit, they all happily ignored each other. And now they have an issue with how she handled something. I just want to say, you weren't involved before, so butt the hell out! *sigh*
Happy Birthday to your MOM!! I'm sure her day was brighter with you there.
She lives alone at 73?!? Good for her
