I’ll preface w/ the fact that my poor mother has a brain tumor. Until recently she'd been ignoring any talk of our wedding. She didn't want to hear about it, other than to insist that she wanted to pay for all of it, despite us not wanting her to have that burden. We hesitantly agreed to let her pay her share & then pay the rest on our end. Now, it's like a flip switched & she went ballistic. She's taken to Facebook, calling me a bridezilla & LYING about my wedding (that my ring cost $15K more than it is--my fiancé bought it so idk why, that I insisted on $600 shoes-I've bought my own shoes for $180). This all after we told her WE would just pay for the whole wedding ourselves when she started throwing her fit. I DO understand that to an extent her memory is clouded by her tumor, but lately she's been downright malicious. It's sucking the fun out of wedding planning & honestly I don't know what to do anymore. After all, she is my mother. Any advice? Do I just plan alone & invite her?
