Why is it even a decision that has to be made?
I used to shoot pool a lot. Then I started doing other things and shot less until I just stopped going to the pool halls altogether. Never thought about should I or shouldn't I quit playing pool.
For awhile I liked to collect rare coins. I don't anymore, but I can't remember ever making a conscious decision to stop.
Same with paragliding, except I realized that I was getting old and lugging the chute up the hill was becoming drudgery, so that might have been a little more of a decision.
But what if you didn't set an appointment for a session and just spent your time doing something else? Not resolving to Never Again, or marking the day you quit on a calendar? Just wander away from it.
It seems to me, if you feel that you actively have to make an effort to stop doing something, that the compulsion has gone too far. To me that would say, Addiction, and I've dealt with addictions. Being addicted to anything is not a good thing, at least not in my book.
But if, as you say, you're not addicted, then just do something else and know that if you ever want to come back to the hobby that you'll have no trouble finding a beautiful provider or two or twenty. No need to put pressure on yourself about it.
