I'm so sorry to hear that you and your wife are having more problems and fights about your recovery. I really hope it gets better for you both. I don't know you or your wife personally to know it would would be of help or not, but instead of having her sitting in on your T session, do you think that it would be possible for her to have a 1 on 1 with you T where it would be more like a third party explaining things to your wife about your reactions, and she could express how she feels/thinks etc.? Not sure if it would be helpful, but maybe. I almost feel like it would be like having a second opinion for your wife, hearing things from someone else that might explain it different. Also, it would be a good environment if she gets angry about what she is hearing to let that out and get feedback as well.

Again, may not be the right situation for you both, but maybe worth a try. I breaks my heart to hear about you fighting at home. Hope today was a better day.
