Kicking him off the fence

[Yoyowife]

LO,
I guess you are right about the background thing. On Memorial Day weekend. My H's aunt told me that H's dad, and both of his grandfathers were adulterers. I had no idea of this until she told me. That's why I don't understand why mother in law is being so cold to me. She went through it with her husband and watched her father do it to her mother. MIL is actually tight with H's OW. They got to know each other because my MIL would go to the office to clean and got to know the OW this way because she is his secretary. My MIL got furious one time because SIL's fiancee sent an email to her that was intended for another woman he had been talking to on the internet. They had never met, but they were planning on it. MIL went to the fiancee's office and let him have it. Her son committs adultery and, it is okay,even though it is has broken up our family. She never even sees my daughters now. Why does it tend to run in families? Is it genetic. I know that is a weird thing to say, but you see it happen so much in families.
