Yes, I've gone through it several times. I call myself a therapy addict because I never want to leave! But I did terminate with a few Ts for different reasons and it was never easy. I agree that the best way is gradually.

First, I would suggest bringing it up with your T. Does he think you're ready to cut down sessions? Also, it's been brought up lately that you can be healthy and functional but still continue therapy. Therapy is growth, and we are all growing. When I terminated with my last T, we cut down sessions very gradually. Actually, I didn't want to do it but had to for financial reasons. It worked well to see her every other week, then every 3 weeks, then monthy after about a year. It took a long time. Then, every few months. She told me that I could see her every few months for "maintenance" and that it would be good for me. Not all Ts agree to that kind of policy, but maybe yours will. It turned out that I am now seeing another T weekly again, but that's another story.

You're certainly not violating any therapy law by continuing to see your T! It sounds like you still need him, and aren't ready to cut down yet. But, I really think that if you bring up the idea with him it will be quite productive. You can determine together what is the best course for you.
