LOL, Cathy, the prayer closet is from Charlyne of Rejoice Ministries. She always went in her bathroom and closed the door... her H wondered if she had some major stomach upsets or something... For me it is the end of my chaise, I get on my knees there. Anyplace you have privacy... it is just a term.
Lots of positives, although they are so difficult to see: 1. Your H knows he is not happy. He is trying to find his happiness. You can continue to show him the foundation of your happiness in your actions. 2. Your H is opening up to you. Like an inch worm, yes. 3. Your H does have days he doesn't drink. Maybe you should write these down. Keep track. Then you will know if it is getting better.
Hang in there.
Relax. Appreciate. Be calm. Laugh. Enjoy. Be secure. Be loving. Be loved. Don't personalize. Don't ASSume. Accept. Be grateful.
