We're going on year 3. I understand about counseling being a trigger. After 2 1/2 of MC, I was glad things were improving enough to start cutting back to 2x a month instead of weekly. It took a few tries to find a good counselor but ours is great. He has helped my WH to learn how to deal with my triggers better so it's been a trade off for me.
I haven't been interested in IC because I don't see any point in dredging things up to deal with with some stranger when WH is the one who I need to clean up this mess.
Perhaps MC would be helpful to you as well but be prepared to deal with the triggers there.
