Your h is baking up quite nicely. He knows exactly what mlc is all about now and he's right....the guilt would definitely have a very serious impact on you.
One step at a time, one day at a time. Once he's fully baked up, I truly believe you both will have a better relationship than pre-mlc. Keep your expectations at zero, listen, listen and listen to what he tells you. Patience is now the key and I do believe you've got that key in hand.
Hang in there.
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.
