I understand from your posts, that your wife doesn't know, what's going on? I don't know how your relationship is, of course, but she seems to be a loving an understanding person. At this moment, you are fighting this thing on your own. If you tell her about it, it can become something you fight together. A wife/girlfriend often feels or senses, there's more going on. I certainly did and it made me very insecure. When he finally told me everything, it was devastating, but also a relief: I finally knew what had changed the man I thought I knew so well and that I wasn't seeing ghosts. I was shocked by his confessions, but what was even worse, was the constant lying. That did more harm, then the facts themselves. I don't know your situation well enough, but to me it was very comforting, that he finally was telling the truth. It made it possible to talk about it and for me to be supportive. It was't easy at first, as you might understand, but it was totally worth it. If you do decide to tell her about it: be completly honest, don't serve the truth in little bits and pieces. Yes it hurts, but it can heal. I always compare to an open wound: when you keep scratching it, it won't become a scar. We know it will always be part of us, but as long as it is a scar, it doesn't hurt. Scars can even make you more beautiful and stronger! Sometimes our scar starts to bleed a little bit, but by being honest and open, we can stop the bleeding. Gabe's video's can help you to explain to her, what was happening to your brain. We watched them together and that was very helpful.
Whether you decide to tell her or not: I wish you all the best and hope to read more about your progress!!
