Davida,
Again, I'm a little new at this to be much help, but I can certainly say I understand a lot of what you are saying. Your wife is not getting over the loss of her husband. She can't understand, I suspect in part because she doesn't want to understand. This can't be happening to her. She's angry at you for taking away the husband she thought she had. My wife is very angry as well and is trying to control anything she possibly can in what is for both of us a shattered relationship.
Maybe our wives will come around, accept who we are, and work with us instead of against us to work creatively to develop a new relationship. Maybe they won't. While apparently many spouses can accept a transgender marriage partner, many others simply can't. I can only hope the best for you and your wife as your relationship either rebuilds or crumbles.
I don't know the law at all so I don't know how much input your daughter might have as to who she might live with if you were to be divorced. I suspect and hope she'd have some say. She sounds like a lovely daughter and one you should be proud to have fathered. Regardless of what your wife might pull off legally, she can't change your daughter's heart; hold that thought and the hope that one day soon she might go shopping with you. How wonderful that would be.
Confused feelings? Well of course! I'm only about a month off from an amazing and shocking self-discovery. My feelings and thoughts are ALL over the place! I know I'm TG. I can't be TG. I'm so very happy to have discovered who I really am. Ugh, this is so, so horrible! How can this be happening to me? I love my wife and I want the marriage to continue. I'm seeing some nasty stuff coming from my wife and I can understand why, but it hurts and I want it to stop. If that means divorce, so be it. Etc, etc.
Elation followed by self-doubt followed by...
I hate all these mixed feelings I'm having but I understand that that's where I am right now. I've got to sit with it and deal with it. At the same time I know I can't just rush into this, but I can't wait to move forward.
I've found this place to be so incredibly supportive; I hope you do as well. We all need to lean on each other. I've been told over and over - GET A SUPPORT NETWORK!!! I'm believing them and working on that. I may be here for the rest of my life and I would be happy in that! But more importantly, I've made contact with a support group locally and will start attending their meetings and hopefully meeting some people who understand what we are all going through. An incredibly beautiful, thoughtful and loving woman on this site went to a fair amount of trouble to meet with me in person. She sat with me for two hours as I poured out my heart and she supported me, as well as giving me some very helpful thoughts.
This is all to say, perhaps it's time for you to find other voices in your life. Reach out for a local support network - you may have to work at finding one and sadly I guess there are areas of the country where they are few and far between - but look! Listen to the voices that you personally find helpful and supportive and while you should and must continue to listen to your wife, don't let her convince you of things you know in your heart to be false.
We have NO idea what our future will hold; we may not know exactly where to go even in our next step, but there is help around you. I don't know how, but I do know I'll be OK. With some help and support, I know you can be OK as well. Don't give up who you know yourself to be. Doubt can be a good place to visit, but whatever you do, don't live there. Move into the certainty that is somewhere within your heart and soul.
