I too went through this when I was married 17 years ago. My whole focus was ME ME ME ME, fantasizing about being a woman, dressing as a woman as much as I could, my wife at the time at first was supportive until I became very self absorbed, she soon began to resent the female side of and we eventually drifted apart until she one day left me for another man.
I think I was a sex addict, I had problems with intimacy and it was much easier to go into my own little world rather than interact with the woman I loved. No drama no nothing..
Sadly it was devastating to lose her to someone else, and at the time I didn't have the ability to see how I was affecting her life.
If I could make a suggestion make a pact with you husband. If he is truly into being forced feminized find out all his fantasies regarding this matter, tell him to rate each fantasy between one and 10, 10 being turning him on the most. Then write down YOUR fantasies and also rate between one and 10, and don't leave any fantasies out, if you are trying to make him happy he should in return make you happy , no matter what your fantasies are. Next you rate his fantasies between 1 and 10, 10 being the least likely thing you would want to do. And he do the same in reverse.
Example. Say for instance he wants to get his eyebrows waxed and wear them at a very thin line all-the-time. He rates that a 10, and you rate it a 10 for not really wanting him to do that. Multiply those numbers and you get 100.. 100 being the points he needs to earn to achieve that fantasy.
Now come up with things for him to do for you that he could earn points to get his brows waxed. Tell him one night of sex as a man with you and no female side of him earns 20 points. (Or whatever you come up with). Or a night of him doing things only you like for example you may like to go dancing but he hates it. So he may earn 30 points for that.
Who knows maybe you have desires to cuckold him, and your fantasy is to have sex with another man in front of him while he is dressed as a sissy.. So for you to get that fantasy to come true you may have to earn points yourself.
This way you can both be involved more in each others lives. If he dresses as a female then you participate in it with him, if he cooks you dinner spends the night as the man you love you grow and bond together intimately.
I'm not going to lie, he may have transsexual feelings.. bi sexual feelings, who knows at this point, but keep doing what you are doing communicating and trying to understand. I think one mistake you may make though is getting upset when he dresses, because he will either see that or sense your body language and close himself off even more to you because he feels guilty. I know it's hard, I know what I put my spouse through, I hope things work out the way you would like.
