Listen to Anvil, Red. You can do it. He's right about the NO contact. You may give in a few times at first, but try it once or twice. You will see the difference in how it feels when you don't answer versus how it feels when you do.
Notice the serenity after you make it through that initial desire to pick up the phone. When you make it a little while after the call that you didn't pick up, you will see that the world didn't cave in and he's still alive. And if something does happen to him, YOU are not responsible, remind yourself of that as much as you can.
I cannot believe the friend is telling you that your AH can't work his program without you. Has he worked it while you were with him? Please don't get sucked into that...it is against everything we are striving for to overcome our co-dependency
Kudos for going to the safe house. It's another step in separating yourself. Look for serenity in any way you can find it, even if it's for short periods of time. Work on the phone thing and keep your head up.
Again, you can do it. You are already fighting to keep yourself headed in the right direction. Don't give up...keep posting.
Know that many prayers are headed your way.
