Are the agreed on times when your other half is also present?
If so, it will only reinforce her negative feelings. My wife knows I dress, but I mostly do so when she is out of the house. She always phones to let me know when she will be home. I also snatch the odd half hour when she has a lay in at the weekend. I have to be well organised to do this.
We never talk about it, but she has accepted that I have a strong feminine side( but not how strong), but she does not want to see me dressed. Ever. So I respect her wishes. I do not wish to cause her any more anguish, so have resigned myself to the compromise.
Is there any chance you can get out of the house? I take a bag of clothes, find a safe spot and change, then have a walkabout in the woods. Of course you need a reason to go out to avoid suspicion. It is easy for me to do because we have a dog ( a cross dressers best friend!) – though she might kill me if she knew I go out fully dressed.
I have been through the guilt and shame cycle myself, so I know how horrible it is. But through CDH I learned to accept my true nature and those days are long gone.
