I never really lied to my wife. When we were dating I thought my crossdressing was in the past and needn't be brought up. Fast forward 10 years when I started dressing again. I slowly brought my desires to her attention. She wasn't all for it at first but figured it was just a passing fantasy. Fast forward another 16 years to today. She is totally ok with my dressing and is open to me someday fully transitioning. I don't think we would have ever got to this point if I had lied to her or hid it from her.
