I only have a minute. Don't move out. Don't enlist that couple's help. It's not likely to be quick.
Be patient, be kind. Do not get into relationship talks with her. Read that chapter and everything on the board written by Jamesjohn about going dark and coming out of the dark.
Click notify when you want help.
Do not give her any ultimatums. They will most likely work against you.
As DQ said, she has experienced your behavior as abuse. You are just going to have to 'take it' from her for a bit.
Slow, patient, kind, gentle.
This does not be a complete dormat....I will help you with that later (today).
Have a great day and hang in there.
