You have agreed to an open marriage so technically you took the chance she would fall in love with another man and now it bothers you?
Why in the world would you even agree to such a thing?
Marriage is about 2 people...
If she wanted to sleep around you should have set the boundaries the minute she came to you with this BS.
Something along the lines of...I don't know - A big fat NOT gonna happen?
Not going to share my wife with whatever Tom, Dick or Harry that comes along and wants a piece of her.
Yeah I took the chance. Its not that. I recognize my failure here. But I trusted her not to do this. I mean, she told me we wouldnt get here. And I think thats what is happening for me now. I feel foolish and stupid to have trusted her.
