It seems like some of them keep pushing and pushing and stating what they want and then when they get what they want, they then monster at us. I can remember the old saying "Be careful what you ask for". My xh didn't really monster when he first left, but when I had the draft separation papers drawn up, per his request and what he wanted stated in them....that's when the full blown monster came out. They truly do not understand what they want and how to go about getting it the proper and decent way.
The only thing I can say is this...take care of yourself and your children. God will watch over him. I know you are worried about him, but he's in God's hands and trust me, your h will have a place to live in no time at all. If the shoe was on the other foot, he most likely wouldn't care if you had a roof over your head or not. That's the mind set that they are in when they monster like this.
Glad someone came to your rescue today. There are angels everywhere and they do show up when we need them the most.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
