You may have had some "ah ha" moments, but I doubt that it was a MLC...transition maybe? Your transition may have helped step his up, but he was going to have one no matter what. He's got a lot of issues to deal with from his past.
Mlc is hard no matter the case, i.e. whether they run or stay at home. Life is very difficult for them to handle and believe me, having them home can drive you crazy because they are there all of the time bouncing off the walls, i.e., nothing pleases them. He sounds like he never completed any of the life transitions throughout his adulthood. He continues to repeat some incidences in his life w/you. He never quite makes it completely and has to revisit them periodically.
In time, he may settle down. You will have to give him as much time and space he needs. In fact, the more you give him, the better it will be for the both of you. He needs to put his focus on his issues and deal w/them.
You have some tough decisions to make in the days ahead. I wish you well.
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.
