Thank you for sharing his text messages and it goes to prove that when they are alone or late at night, they do think about things quite a bit. When it's during the day and evening, they have things to keep their focus elsewhere. Your h's depression is going to start to get deeper, but that's following the MLC trail.
OMG, what kind of father would tell his son that if he hadn't left him they wouldn't have had the lifestyle they had? That's awful! The poor man feels like a failure and an unwanted child no wonder he's so confused about life. To him, being alone will ensure that he causes no one harm or have expectations of him. BTW, I give the man credit for raising the issue w/his father. It has been bothering him for quite some time.
You did a great job w/validation. I'm sure you were surprised to receive these texts. I'm sure that there will be more texts to come.
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.
