BTW, you mentioned how your home was so serene while she was in rehab. Same here, I believe it was my HP giving me a test run to gather my confidence that I could indeed do it alone.
It was a great lesson and chance to catch my breath. Living, if you can call it that, with an active alcoholic was too much for me.
Sounds like you are in a good place with your clarity. Since you've asked her to leave, prepare yourself for the onslaught. She may pull out every dirty trick in the book.
I called the police on mine after she slapped me so hard I had a black eye the next day, and I almost went to jail, the only thing that saved me was I hadn't been drinking. Protect yourself, do no wrong, be above reproach till you can get her out. Good luck.
You sound like a good man.
Thanks and God bless us all,
