what ever I am doing seems to make her more angry and hurtful towards me.
I know that things suck right now. And, like the others, Im sorry for you.
But what you posted here does NOT mean that youre doing the wrong thing. Its OK if what you are doing makes her angry. Thats on HER, not on you. You guys agreed to stay out of each other's rooms, and then she kept going in yours. A padlock was a great idea. But of course shes going to be mad; shes used to getting what she wants all the time! One thing that Ive learned: Peace does not mean Progress.
If you were giving her everything she wanted the last few months, youd be no closer to R than you are now. At least, now, you are learning to stand up for yourself and to gain your self respect back.
You arent going to stop her from leaving. But by becoming a man only a fool would leave, you give yourself a chance she may come back.
