I Live In a Sexless Marriage

My wife and I finally had a talk about my feelings for her, which are that I care her as a person,last Thursday. I confided in my daughter whose visiting, who told my wife. Which just confirmed what she already knew. It has gone surprisingly well so far. I'm still staying because of the grandchild we are raising. My wife's only request is that I be discreet and move out if I start f###ing someone. I hope y'all don't mind but I felt a need to share this. Is it wrong for me to be sad but happy at the same time?
