My wife of 38 years passed away just over two years ago. She knew about my dressing and was supportive. There were somethings we had been able to share and I kept those in my wardrobe both as a reminder of her and for me to wear from time to time. The majority of her things were donated to charity, many of them to a local Pride Center wardrobe.
It's a difficult path to follow regardless of what choices you make. With time some of the choices become easier, so if it doesn't feel right to you don't feel like it's necessary to choose right now. You can wait.
