I was closeted and have been married to the first and only now since 1982, coming up on 34 years.
I was so afraid to open up that my wife had created this whole scenario in her mind that I was having gay affairs somewhere. I wasn't, and I have been 100% faithful all along. But needless to say, this was causing us huge problems.
Finally, because of the constant fighting, dysphoria depression, and because of my utter disgust with myself for being too cowardly to tell the truth I felt that suicide was my only option. So I planned it and rehearsed it in my mind over and over. I got as far as physically rehearsing the actions with my pistol then realized that I didn't really want to die.
So with absolutely nothing left to lose I told her I was trans. That was the single hardest thing I have ever done in my life. The amazing thing was that once she understood what was going on her anger evaporated. That was around ten years ago and we are still married, happily even.
So, in my mind at least I have elevated her to the level of sainthood. :-)
Sometimes the fear of what might happen is much worse than the reality.
