well to be fair, you told him you were filing for divorce on July 4 or thereabouts. that's not a full three weeks yet. you have already agreed to a move out date, giving him six weeks to do outpatient. which he may or may not adhere to.
he'll likely negotiate, plead, deflect, ignore, stall, whatever to keep from actually having to MAKE any changes. it's worked for 20 years......
