Regardless as to whether he is in MLC or a Walkaway, you would still proceed as you have been, i.e., give him plenty of space and time.
I know it's difficult, but you've got to keep the focus on you. The more you think about what he may or may not be doing, will drive you crazy. He may be at his sister's home doing chores, watching TV or the computer/phone or just chilling...but whatever he's doing, he hasn't forgotten you are what has been said.
Hang in there and try to enjoy your day. He will contact you when he's ready.
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.
