WR, No, it's not bad to say he blamed his parents for a lot of the things that went wrong in your lives. Deep down, he had a good idea of the whats, why's and whens. He just didn't realize how much they would explode into this monster. No one did. We were never told about such things growing up. Mlc was a hush hush topic for many years and yes, many folks early on died very young, so people didn't see this crazy behavior. It all began to get some attention when Bill Clinton had his little tryst in the White House and from there, many more have come to light.
Maybe your son is thinking that Christmas may be a time that his dad will want to be w/his family. I sure hope he's not disappointed. That would just crush him.
I do hope you'll feel better soon.
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.
