So this will be a long story of what is happening in my life. After 18 years together 17years married my wife started cheating on me last july. The snake was a friend of hers from our church who a year earlier lost his wife in a car accident. He was engaged to another woman while sleeping with my wife. At the time she was 36 and he was 63. She told me after she wanted to be separated. The day after we filed is when she told me that she has been seeing someone. We were in the process of buying a much more expensive house and I had taken a big 401k loan out for the down payment. My wife eventually told my kids who it was and they told me. I acted as if I did not know. Eventually I contacted his fiancé and in the middle of august my wife and the snake broke up. I told our pastor about what was going on which may have helped end the affair. My wife moved with our kids to the new house and I stayed at the old place. As of the first part of September she is going out with an ex boyfriend from high school. I am paying child support and I get mad when the boyfriend is up eating food that I helped to buy. She is a 2 or 3 bottle of wine a day drunk. I am done with her and could care less what happens to her. She is selfish and blames the kids when they hear her and her man having sex. The kids are definitely not at fault and should never be blamed for that crap.
