Tough to be going through what you are going through that is for sure, I had two very serious health issues within a very short time frame, I kept all my clothes and I am so glad I did
The thing is, if your wife knows, then you don't have to hide them and if you keep them you have a choice to dress or not, if you get rid, you have no choice and actually mine were just as important to me during my illnesses as they ever were, somedays it was just knowing that they were there that brought a smile to my face and made me feel good inside
Stay strong, keep positive and work though it, I am still here and dressing more than ever
Good luck and best wishes
