After my mom passed away, my current wife informed me that the two of them talked about my dressing and my mom was very aware of me wearing her clothes, even though my mom never let me know.
Finding that out must have come as a shock, both that she knew you were CD and that she talked with you wife about it, unbeknownst to you.
The crossdressing community is one that needs to stick together and continue to be there for each other for whatever one needs. We are always trying to improve the forum to better serve the crossdresser in all of us.
