Good luck.
My ex did the same with me -- got into my emails and found every website I had ever posted on, not just about addiction. She read everything I had ever posted. Here especially. She would cut and paste stuff I had said and email me about it and question me. It was miserable. We've been apart for some time now and I'm not convinced she's quit coming here to track me. I wish I could give you advice but I can't, I'll just wish you luck.
BTW, I'm the alcoholic. Not her.
Also, talk to a mod if you want to talk about making some changes so things are more private.
