What I hear in that email, P, is guilt and a tinge of missing you. Seriously. I know it sounds distant to you, but he is telling you a lot more than he needs to.
Omy goodness yes! Could it be... Your H is finally getting a dose of reality!!! Good!
Does he seriously think you and he will be pals exchanging emails and letters?! I think these WAS are so scared to reach back... Whether for R or to simply test the waterss or even just to apologize and yet when they do w/ something like this our reaction is always... How the heck dare he think this is ok!
