I Am Too TUPID!

I got married at 27 to a hot girl. It was a short dating period and we were off. First 2 years were good. Then a snag...
I came home one day very early. Computer outage at work and they said "go home". Got home around 11am. Walked in and no one obvious. Yelled for wife, no answer. Went down the hall and into the bedroom. Found my wife naked, face down, tied to the bed spread eagle. She was crying as I panicked and tried to untie her. From the condition of her pussy and ass it was obvious sex had occurred. She was sobbing and claimed there was a break in and she was tied up and r**ed. We lived in a one story house and the window was open. She said the guys (as in 2) ran out the window when they heard me. I wanted to call the police but she did not. We went through the night arguing about it. She said she was embarrassed, didn't want a trial. Blah, Blah. I gave in and we went on.
A year later I found out (with proof) she has been cheating with multiple guys. And yes, she admitted 2 of them were the guys who had her tied down. It wasn't r**e after all. Just her and her friends. Not too bright here...
