Ditto all of the "This should be in Lifestyles" stuff. I really shouldn't be encouraging your behavior by posting here. BUT as a woman who's gone through some codependency with partners kind of s**t:
It sounds like you need more stuff going on FOR YOU in your world, because it looks to me like you're trying to soak up all of his stuff so you can be the center of his universe. Do your own thing, do what makes you happy. Present your life however you want to. If all the YOU that comes out of that expression isn't enough to keep him at your heels, trying to take up his hobbies to bring him around is a waste of time. Whole, interesting, well-rounded and -adjusted people are interesting to others of the same flock.
