I would love to be completely opened and honest with her but the way she has said negative things about cross-dressing over the years.
When the Caitlyn Jenner thing was in the news my SO said "he's all messed up" and when I would try to say something positive about it I would get shot down.

I reminded her that she knew I cross-dressed with friends in my teens and that I started at 8 after my sister dressed me up.
She said she always thought that was just fooling around, not cross-dressing!

She also said it's creepy that I want to dress up, and if it doesn't stop she'll tell my son and he'll be crushed.

I feel at this point telling her I can't stop would be a big mistake. She says I'm ruining Christmas.
