Please do not make promises you can't keep.
I think maybe you should see a professional but more to help your wife see it's a part of you and not something you would be able to stop.
She just is not understanding it at all and I think you should not gotten rid of anything.
You might think this is a a solution for a quick fix but be honest with yourself someone that dresses since age 8 is not going to stop. I have never heard of anyone that have just quit. If you dress ( and you most likely will) she will see it as a betrayal and it will be much worst. There is nothing wrong with dressing.
So that's my advice see a professional and include her in sessions after a bit so she can really understand this is not a big deal.
Just my 2 cents
