It's time!!!!!! Time to let go, drop the rope, detach with love. You are too wrapped up in her to fix and love yourself. You have to love yourself, more than the craziness she is carrying on with.
How do you deal with it? Show her you won't tolerate it. Start to distance yourself. You don't need words, you need actions.
You need to research tough love. It has nothing to do with being cruel. It has everything to do with not allowing disrespect and respecting yourself.
Get the book, "love must be tough", by James Dobson.
Reread what Sandi said, about, if her husband had did certain things, it would of jerked her out of her fantasy. She mentioned what her husband actions were a few times, and focus on her actions when you reread her post to you.
