DADT=="Don't Ask, Don't Tell". In other words, your significant other knows that you crossdress, but they don't want to see it and don't want you to tell them about it. It totally sucks. It's honestly in many ways as bad or worse than having a significant other who you haven't come out to. You have to hide your clothes, sneak around and not get caught dressing, often times other feminizing body changes like body shaving, ear piercings, etc. are not "allowed". The only positive part in having come out in a DADT relationship is that at least you can purchase clothes and not have to worry about what happens if your significant other finds your "stash". On the flip side however, you get to deal with all your significant other's jealousy, anger, hurt, etc. from knowing about your cross dressing. So yeah I'm not sure it's any better than being in the closet. It's definitely not an enviable situation.
