Grandma on fathers side

Nikki • Mommy of 2. Daugther Lanae 5. Son Noah 1.
My boyfriends mom has became extremely annoying!!!! She was suppose to give us our baby shower and she cancelled last min so we threw our own but she got us 3 things from the dollar store! Meanwhile she on Facebook bragging about stuff and she hasn't done nothing! I'm so frustrated and it's causing a wedge between him and I. I'm just so unhappy.
