Update:
My wife dragged it out of me today. Were talking about what to do, and I said I wanted to get a blouse. She then talked about why, and basically forced me to talk about it. She knew I liked the cross dressing, and now she knows everything. She gave me some of her old clothes that no longer fit her, fit me perfectly though. She was angry, and a bit upset, but understanding at the same time, and she said she was fairly certain that this was what it was. One of her exes is a MtF also, and she helped him along. She doesn't know what she will do if/when I progress as she is not into women, but she loves me, so....I guess it went alright, even though I wasn't really prepared to come out to anyone yet.
Thanks everyone!
