You stopped doing things you liked, enjoyed, were good for you because there simply wasn't enough time in the day with a wife and kids.
Now you have the time.
While you are doing these things...like say... uhhh building a model airplane.
You aren't looking for another relationship. (This is important)
So your not re-using dusty skills and relationship tactics from your past...instead you are working on yourself and sharpening these tools, discarding the ones that don't work, and getting new ones.
You're taking a hard look at yourself and redefining you as you want to be...not trying to redefine yourself by what someone in a relationship wants.
...
Or something like that. : )
