I understand why you called OW's XH. Not sure why you bothered to tell your H, or really why you call him at all. But hopefully now you have that out of your system and can move forward with your life.
It does help confirm that there is not much point in looking at positives or negatives when it comes to WASes because we have no idea what else is going on. You probably suspected you had done something wrong when he went distant and probably felt things were going right when he was seeking out sex. When things do come to light, it becomes clear that their behavior has everything to do with them and nothing to do with you. But it's all part of the process. We have to learn to let go. And I mean actually let go. Move forward and not look back at what could have been.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
