As someone in a long term relationship (married) I would certainly want to know I don't care if it was a drunken one night stand, a full blown affair, a cyber affair, kisses and cuddles, if my husband was doing that behind my back I would sure as hell want to know, and I wouldn't care who told me the mailman, the mistress, her mother... If I'm being faithful and giving all my love to my husband I expect the same from him. Why should he get a pass, and good on your friend for doing what a husband is supposed to do for wife BE HONEST... Then the wife has the chance to decide if she wants to stay or wants to go. I know if it were my husband I would hope it was the best s*x of his life because when I got done with him he would never be able to use his member to break another heart the way he broke mine... What a jack@ss... Cheating is not ok no matter the excuse... Marriage is marriage remember for better or worse not ill be faithful to you as long as you iron all my shirts, have dinner on the table by 7 everynight, pleasure me when I say, etc... That's just my opinion I think you're friend is gem for wanting to do something she doesn't have to do.
