Hi Jess,
I'm afraid there is no magic pill for that. It is all up to you and it is all a matter of will power! The feelings and the desire to dress like a woman will most likely never go away, but if you set your priorities toward your relationship, and the dressing cannot be part of that, then you can stop acting on those feelings!
Just will power, nothing else.
I did!
Hugs
Suzie
