Your last thread asking for advice on the situation with your wife prompted me to go back through your history and read your posts. What's happened now is terrible, but not surprising unfortunately. You were flip-flopping on your dysphoria, trying to repress it, and leaving your wife in the dark, and once she found your account, it probably became very clear that an issue that she very clearly wanted to discuss with you for a very long time WAS being discussed, online, with strangers. Details about her relationship with you were exposed to people she does not know, and yet you couldn't be honest with her. As much as you love her, and she loves you, there is a great deal wrong with this picture Tegan. You have brought up the subject in the past with her, but her initial reactions of shock (which was pretty normal) led you to further repression (understandably). Unfortunately, it seems, there wasn't many places it could go that didn't end on this very path.
Personally I think your wife is being extremely unreasonable and unempathetic. You didn't wake up one day and decide to be a badger. Gender Dysphoria is a medical condition that you've suffered with your entire life - hell, you've never even known what it is to feel normal in your skin - and she's been (from what I can tell) the only reason that you have not transitioned already. You have been giving up the only means of happiness - and medical treatment for your disorder - for the chance that your relationship could work. And now it isn't, and she's acting like you're a villain in all this. Yes, you should have been honest and upfront, but seriously, she clearly doesn't get what GID is, nor would I attempt to get her to understand. She seems bitter about the whole thing (again, understandably) but extremely un-supportive. I'd personally want to get away from the situation, but if you don't have anywhere to go, you really should tell her as much and stay home until you can figure out somewhere to go. It takes two to tango, I know, but I don't think you're being unreasonable to want a bed to sleep in and some time to get your life together. It sounds as if you're letting her call all the shots, and from your depressed, exposed, vulnerable position, I can understand not wanting to challenge that - but seriously, haven't you been sacrificing long enough? It's time to put yourself first. Get rid of the dark thoughts and put yourself on a path to happiness. This is a chance to become the person you've always wanted to become.
I'm sorry if I'm being too direct or confrontational, it just sounds like you're in a lot of pain and I want you to be okay. GID is hard enough, but you can get through this, and you can make your life better! Yes, you love her, but if she doesn't accept you for who you are, medical conditions and all, your relationship is not worth holding on to. You will be better off in the long run. The words 'my wife found my Susan's account' sound shameful, guilty even. Susan's is a SUPPORT group for a MEDICAL condition. Would you feel bad if you had cancer, and your wife found your online support group for cancer? It upsets me that culturally the whole perspective on this seems warped because of what's associated with being trans (it also upsets me immensely that people rally to remove Gender Dysphoria from the DSM, but that's a rant for another thread).
I really wish you all the luck in the world Tegan <3 thinking of you!
