CMF, good for you! great that you have started going to meetings. that will help you soooo much!
It is so hard, to stand up for yourself against their arguments and accusations, but you will be alright.... just take care of yourself, and keep posting here. You cannot imagine how many have been in your very shoes. they must be very worn out shoes, you know?
If he gives that key back already, you are very blessed to not have more of a fight on your hands. I hope things go smoothly and that you find your serenity, and begin a new life for yourself, where you can live in peace and find your joy.
hugs
