I hate my mother in law. She's a complete bitch to everyone, not just me. The wife included. For some reason Mrs FP still defends her to the death. Very strange. 
yes. this is my exact situation, but she thinks she is the most polite person in the world.
I'm with ya broseph. She calls at least 4 times a day as well, and if Mrs. FP doesn't answer, she calls my phone. 
sounds like we're dealing with the same woman. how long have you been married/how do you deal with it?
Year and a half. Everyone in the family knows I hate her mom, the wife, the mother-in-law, the father-in-law. Everyone. Weird because I love the father in law

If I have to be near her I'm just normal, only I avoid talking to her if possible (it never is) I don't really care to make a big deal out of my hatred for her, although she tries to bring it up sometimes (something I find extremely strange)
