I would add that you have to change the way you are thinking. You are speaking in terms of what your W is doing to you. That isn't healthy. People don't "do things to" a leader. They do things to victims.
I don't think you are trying to be a victim, I just want you to be aware of a way of thinking that can lead you to a bad place. Seligman calls this "learned helpessness."
You aren't helpless b/c YOU decide how YOU will react to what she does/says. Yes, what your W is doing is hurtful and vindictive, but YOU decide how it's going to affect you. Take back that control while at the same time processing the pain that undoubtedly is there.
"Handling it" doesn't mean you won't hurt. It means you know you are stronger than the hurt.
