My wife of 23 yrs was just like that! Not just with bicycling but with anything that didn't involve her. Drawing, metal detecting, bike forum, anything that I would take pleasure in.
But thats all changed now. Turns out she's an addict! Vicodine and other drugs her docter had her on. Also a little booze problem I didn't know she had while I was at work.
AA changed her and she let go of my leash. She's so involved in the "steps" now, I can peddle all I want to. All day long.
God, I'm so lonely!
