I concur with Laura; read what Char GG said over and over again.
STOP making the promise that you won't do it again. Crossdressing is who you are. Promising you won't crossdress is equivalent to you promising you won't have chromosomes. It doesn't work. There are countless stories here of crossdressers who tried and failed to suppress these urges. You could assume there's confirmation bias here; only the people still on the forum are unable to suppress the urges. The ones who were successful aren't here. Except, that doesn't work either. Try searching the net for success stories of people who have successfully purged and suppressed the urge to crossdress more than 10 years. I'll save you the time. Those stories aren't out there. You are a crossdresser. Purging is wasteful. Suppressing is harmful.
Now, MANAGING is another thing entirely. Lots of crossdressers here have Don't Ask, Don't Tell (DADT) marriages. Lots have wives who know, but don't want to see. You can fit into one of those paradigms and manage this so that both of you are happy about the outcome. An honest, open, non-critical conversation with your wife (from you and her) can dramatically help work through this. You can also go to counseling together as well if both of you are willing. Know this though; you don't stop being a crossdresser by going to counseling. Going to counseling is helpful for how to manage your relationship with the presence of crossdressing in your lives. Perhaps you can get to a DADT agreement, or accepting but don't want to see arrangement. Something.
The status quo is not going to work. All it will do is make your relationship worse.
Let us know how it goes, feel free to ask us questions, and bon chance!
