I had something like that and it took 7-8 years before I "accidentally" told her enough that she was guessing in the wrong direction and I realized I either had to set her straight or there was no point in my seeing her, therapy would all be a "lie". I set her straight and was really really surprised, pleased, relieved, etc. at her response. See if your problems don't come from how you think the other person will respond. We can't know until we tell them and see.
