I wish I saw your post yesterday! Yesterday the wife, kids and I went to my MIL house for lunch then over to our friends to watch the Super Bowl. Everything was fine all day until we got home and put the kids to bed.
She just blew up at me about everything, I would walk away and calmly say lets talk tomorrow. Then 5 min later she would be back screaming at me, asking who I was texting (I was playing a game on my phone), telling me she hates me, she should have never married me, she will get a lawyer and through me out of the house, that I treat her like a piece of property,etc.... I even tried to go for a walk but she followed me and said she won't go home.
I eventually took the bait and told her in not very nice words that I'm not the one having an affair, who is leaving for another man, and filing for divorce. This just got her more angry and it went around in circles for about 30min.
She left the house to morning to drop off kids and go file. I'm fighting a cold so I'm home in bed, maybe a little sad also.
