Mother in law Rant

I cannot stand her. She doesn't do anything for my husband or for my child and makes sure she points out that's his step child. She never had a dad and at our wedding he vowed to be her dad and point blank period, he is. She only tries to be involved when she gets something. She even had my husband getting her father day card and present. He HAS A DAD. She is a piece of shit. I've had it up to the clouds with her. Honestly I could go without ever seeing her again but she is his mom so I have to play nice. God knows she is messing with the wrong woman's husband and child. She has one more time of standing him up or popping off at the mouth about her and I'm going to snap.
