Put between a rock and a hard place

This has been an unbelievable time for me. I am reeling from a predicament I was thrust into. It all started off innocently enough. A laugh here and hug there. Just as with all my friends husbands I expected the utmost honor. I was wrong. A friends husband contacted me for much much more than advice and a joke. I was put into a place where I had to tell my friend her husband is a cheat. This is not the first time this has happened to me. Men think I am cool and will "go there" just because I am open an honest about who and what I am. What they dont realize is that above all, I am honest. I have been a wife who trusted her husband who was a cheat. I have been lied to. I know what it feels like and why the wife needs to know when her husband is risking her life buy screwing around on her. I was petrified for her, for our friendship, for the group of friends I know her through, her family, and just about everything she and I have anything to do with including my reputation. I was sick for days trying to decide if I had misunderstood what went down. I re-read the conversation between us. There was no misunderstanding it. Then I thought ok maybe he was just living out a fantasy by talking to me that way. So I let it slide. I let it slide until the next time we went out and he was all over every woman but his wife. It made me sick. I knew then, what I had to do. I dont know why people do things like this. The whole thing was so insane, selfish, and hurtful. I hate what he did to her. I hate what he did to me. I hate what he did to our friendship and the friendship of the girls. I despise what he has done to his family. He reminds me so much of my ex husband. So sweet, funny, and understanding. The only thing he really understands is his sex drive, everything else is a lie. Its so sad, and infuriating. I have been crying all week.
