Wife / Girlfriend rage
^^^ You said you love her more than life itself, you answered the part about what you will do. Love is funny emotion.
You asked what We would do.
I figure you can't fix stupid or heal bat chit crazy. I guess you like a challenge!
Me, personally, I care NOT for such childish, stupid behavior...I would show her the door after I moved all my valuables and myself OUT.
But I'm not Anne Landers or whoever that advice lady is.
