@SageFox
I am sincerely sorry for what your going through and I can relate almost to the letter. I am prior USMC ( discharged over a year ago now ), told my fiance of 2 years ( about 4 or so months ago ) that I had always thought of myself as a woman and that I one day may wish to fully pursue correcting my body......her immediate reaction was to break out in tears, a little bit of anger tword me....she freaked out a bit and couldnt look at me for a good 10 minutes or so. Eventualy through her tears, she regained composure, and we began to talk about it. I reassured her Nothing would change but physical appearance and that if she truely loved me, it would be no different then if i lost a limb, got really fat or some other such physical transformation ( which she admited she would love me through any of those ).
The following day she told me she was ok with it and I felt she was being true. I think what may of helped, is I didnt immediately jump into transistion and gave her time to relize im still the person she loves. We still talk about it from time to time and shes completly ok with it......but she has alot of self confidence issues of her own and I am afraid she may be embaressed when i start going more full time.
I pray your situation improves with time, and I don't know how recently you wrote that letter, but hopefully let time heal her worries a bit.
Please feel free to message me on here if you'd like to talk further, vent, or whatever as we are aparently in near identical spots as per looking to transition and I have a military backround so I can relate with you there

Hopefully when you get back, you will be approaching your discharge day, as I really cant see transitioning while still serving. Good luck with everything, keep us posted. talking about it hear should clear your mind, and please dont have any super depressing thoughts while all alone and near a rifle. Things will get better! I promise!
