you then are just taking your way of thinking into account, not the one of the other person. Lying by omission. I have nothing against trans, but i would feel violated. If you want to be respected, then do the same.
Stop being a friggin pussy and be a man. Leave that woman, she dosent loves you nor gives a fuck about you. she needs you? too bad for her, maybe she should have thought that before hitting and treating you. Is she is stressed? sad, but all the world is under stress sometime and using a knife against you partner for no real reason is not a normal response, nor a healthy one. Leave while you can, be alive, be happy, be awsome. Let her drown in her misery
