WHEWWWWWWWWWWWW..now that's over with! It's something that we all think about and stress over, but for you, it's over and you handled it. Ok, so it's a goodthing that people can't see the dread we feel. The best part is that it was Ry's day and for him it was a great one.
You know K that I have my own theory on how and why this all went down. I think he brought OW because he has no one else. You have your WHOLE family and he would have been alone in the crowd. Besides that, I would imagine that seeing your family after all this time, and their being so gracious, would leave him with much to think about. Even though he chose to leave, and now finds himself on the outside looking in, he has to be thinking about what he gave up and whether it was worth it. They were his family as well, and with all he's done, they still extended an olive branch. Pretty cool of them!
It's been long enough with a big enough separation from you, where now things just might not look as they did 6 years ago. I know someone who said that when they were in this position and enough time had passed, they now saw that it all could have been handled so differently.
I would bet anything that your thinking he probably feels as if he got away with something is way off base and nowhere near what has been going through his head since the graduation!
