I guess not that slutty, but true.
Wife grew up friends with a girl in the neighborhood. They were close, only girls in their respective families. They got married and stayed in tough but lived 50 miles away from each other. Every six months or so my wife would drive and visit her friend. Eat and shop together. No big deal.
About a month ago my wife said she wanted to talk to me and show me something. It was a text from her friend asking her to come visit, how much she missed her kisses and touches and wants to lay naked in bed with her again, especially since her husband died.
Wife explained that this started when they were 15 and while it died down while they were married, it never stopped. Wife felt guilty about keeping it from me. I never felt there was anyone else, she was always very sexual in bed and viewed her friend as a friend, but thinking back at all the weddings and funerals we attended, she always seemed "close" to my wife.
I thanked my wife for being honest, but told her to tell her friend she won't be seeing her again. She agreed.
