Dear Steve and Shirley, I’m in my late forties and my sister-in-law is my best friend. My brother is cheating on her and she found out from their 6 year old son. I was keeping their son and we went to visit my mother, his grandmother. Well, my stupid brother had his girlfriend over there, having a fish fry in the backyard. My mother was in the house mad as heck, but my dad was outside with them because the woman has a really nice body............................
