Ugh,
Judy, yes you have played the sympathy card here long. And based on older posts, if true, then you would not dress just once a month. In fact, I did the math once, and your description added up to dressing twice a week on average for over ten years.
But to my point. While I am a big proponent of trying to work it out, if your big concern is that leaving her is financially disastrous and you'll die of lonliness, I would suggest that you need to see a therapist. Not for TG, but for codependency. Quite frankly, I get the feeling that you are in one of those love hate relationships that is toxic.
It might be better to be broke and alone, then to live in constant dread. You might piss her off, you resent her domineering, nothing is ever right. Maybe you need some serious time apart. Does she appreciate anything about you. Do you appreciate anything about you? Ever hear of the Stockholm effect? Or maybe you need to stop living a fantasy, and either fish or cut bait.
Sorry to be so harsh, but you seem stuck in an endless loop. Do SOMETHING!
