Glad to hear you had a good session. His efforts to transfer sre really meaningful and I'm sure will help alot.
There is another book that I read titled "How to fix your marriage without talking about it", by Patrica Love and Steven Stosky (? not sure of his name spelling). I got alot of good insight out of it and while I can't use some of what they suggest (ie; hugs etc), I do inplement what I can when I can. It talks about womens fear and mens shame in a way that was really illuminating to me.
Given that I'm not nearly where you are, I don't know how helpful this may be, but when I get angry I usually do something physial first (even walking is great) and then I do my "I'm grateful" list. It helps me refocus.
I hope you can let him back into the bedroom and your heart. You're right that it takes baby steps. Take care and be well. Love, Grace
