I have to agree with Koffee. I'm a guy who gave up a lucrative day job making "mucho" dinero, for two years, to care for my two daughters--1 and 3 years old. Priorities and long-term rewards are what everyone should focus on. (I still continue to teach at the college two nights a week, but would have given that up too for my daughters.) My wife chose to continued to work as the insurance package was better and she had no other part-time work available. She would have gone nuts only watching the girls. As far as addiction is concerned, cycling is a new one for me, and I "will" control that, since my previous addiction, golfing, was placing a great strain on my relationship. Pull him out of the loop for one week, if possible, so that he can gain some perspective and see the possible loss; it's a little hard to gain some clear perspective when your in the thick of things. It's alright to join him in his hobby if it truly is your thing, but if it's not, then as Koffee suggested you are giving up part of yourself. (I'm reading through the discourse.) Jung said that only when we are walking in paths of our own desires, are we truly authentic and complete (happy). Good luck!
