Hi poofymommy,
You story mimics that of my wife's to an extent. The timeline is eeriely similar. We've been together since March 2007, married March 2010, I cam out to her January 2016. My wife unfortunately is not a member of Susan's and therefore not really an option to talk with.
I am glad to hear that you don't love your spouse any less because of this. It is incredibly difficult to come to terms with. I showed almost no signs of being trans to others until around November 2015. That was when I decided that I was going to allow myself to indulge in crossdressing and not care what the world thought. My wife knew that I occasionally wore panties before and was okay with it. Somewhere around 2011 we were being experimental and I got to fully dress. This was a first for both of us. She was incredibly uncomfortable with it and the physical appearance of it weirded her out. So it was dropped and not brought up again. For me most of the signs were internal and others were not privy to my thoughts. I had believed it to be just some sexual fetish.
After beginning to experiment in November I discovered how liberating it was and began to question everything. I researched the subject and pieces started to click into place. I found that I had been repressing my feminine side for almost my entire life and that had turned me into a terrible person. I allowed myself to start expressing my feminine interests and discovered that it allowed me to be a better, more patient and caring husband, father, and person.
As has been stated communication is critical. Your husband came out to you which is an incredibly brave act. I do not know your husband, nor can I divine any information from your post so I cannot make any reasonable assumptions about his frame of mind or experiences. You know him and are now beginning to know all of him. Keep the lines of communication open and try to discover more about his experiences and motivations. It may help you to come to terms with things better. Constant communication is important, not just a one off situation.
You are seeking a perspective from someone who has been through this, which is a big step that should be quite helpful. It is unclear what specifically you are having problems with. It sounds very much like the appearance or just fact of him presenting as female is the primary part you can't tolerate. One thing that I can say is that appearances can be tolerated over time. It's a process of adjustment. Without knowing more details I can't comment on other aspects of it. My wife has been incredibly supportive. She still is somewhat uncomfortable with the appearance of me en femme. Slowly we are adjusting.
I hope you find the help you seek. I also hope things go well for both of you.
