There are quite a number of MLCers that move a long distance from where their home base is. Some move from one coast to another and some even move from one country to another. It's running away, hoping that new scenery, new position, new people are what they need to jump start their "good feelings" again. To them, it's an adventure waiting to happen.
He will tell others anything to get them from asking questions about his decisions. Right now, all he's thinking about is himself and what he needs to feel alive again.

Why are you saying you are a terrible person? Is that what you think of yourself? If you were such a terrible person, you wouldn't be on this forum trying to understand what he's going through. If you are thinking that this is what your h is thinking about you....well, that's his perception right now, but hopefully it will change while he continues to travel on his journey. BTW, while he's traveling, if you have anything that you need to work on for yourself, now would be a good time to do so. Whatever changes you make, make them for you and be happy w/them. Do not make the changes to win him back because he will see right through them. The changes must become permanent.
The man upstairs has a way of bringing things to light so that we can better understand that this is his journey and that we need to detach and allow them to make their own mistakes in order to learn from them. It's also his way of telling us to keep the focus on us and our families during this time.
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.
