At the begining of my separation, my mom told me that the worse thing you can do to someone is give them what they want.
Your wife says she wants you to leave her alone.
You might be right, she really loves you and wants to be with you.
However, if you stay around, she may never realize that she truly wants to be with you. Right now, it sounds like she's projecting all her hurt onto you. If you aren't around, she won't be able to do that for long.
I could be way off base here, but I suggest committing yourself to a certain time of being dark. Can you handle 2 weeks? Set a goal that you think will cause her to wonder!
I hope that helps!
I'm sure others will have some great suggestions too!
