I lived this life for far too long. Each day you don't face your fears and start HRT is another day you hurt your wife, and yourself. HRT changes everything, and within a day, or two the dysmorphic OCD loop is broken. You're mind, if you're indeed trans, will start working the way it was meant too. You'll be calmer, sweeter, and sane. That's a hell of a lot better than kneeling in the shower and crying. It't time to man up and start HRT for both of you. In time she will come to understand, and even love you. I'm not saying that you'll have the ideal marriage, or that you'll remain married. Whatever happens will be for the best! Many wives do remain and gain a shopping buddy. Trust me. Estradiol has shown me the joy of being alive, of being authentic, and loved. I have reconnected with life. I started HRT May 7th and I already see changes, especially in the eyes and cheeks, and of course, skin.
Good luck :-)
