Oh Kira and Melissa!
You both are in a very tough place right now. Please , believe me I know the feeling as, I am sure many others here also know of taking two steps backward.
Kira, how long has it been since you've come out to your wife? It almost sounds a bit similar to my experience when I told my wife about this over four years ago. But, does she understand that you are transitioning? After all, you are on HRT! Does she go to therapy sessions with you? If not that might be a good place to start. When I first started therapy, my wife told the therapist that "if he was going to go parading around town as a woman", she "was not going to be married to me anymore"! It kind of threw me into a tailspin for a while and I really thought my life was over! She also was worried over what her friends would think/say and the biggie, what her boss might do if he "found out". However, after a few month's and a few more sessions she started to "get" the idea that this was not going away, ever, and that she needed to make her own choice, stay or leave. I'm glad she chose the latter. It certainly did not happen over night and, it did feel like it took forever to make progress.
All I can really offer is that hopefully time is the answer and after enough of it maybe she'll realize that this isn't going to end for you either. Hopefully, she'll adjust to what you need to do and, will be there with and for you. Now that she knows you feel the need to carry a purse, given some more time, possibly she'll relent on her rejection and support you in doing so. But, as painful as these issues are, you have to support her, too. Her fears and worries are not completely without merit. This is all an unknown quantity for her. Rest assured though, these issues can work out in order for you to proceed and at some point feel complete. I know, it did for me!
