Quote: I am very confused about going up to stay at his place for the first time even while he is building bridges with OW1. He evidently PREFERS to stay with her than me when in town. I suspect it could be in part a matter of simple convenience as she is right in the town centre.
Just have to tell you - stop with the ASSuming. You don't know what's going on over there. Maybe it IS just a matter of convenience. Maybe H is breaking up with OW1 for the last time (funny she would have him there after her response to the email, isn't it?) - trying to clean things up in his life as well as his house before you come up there. Or maybe all of this is still part of his fantasy of remaining "friends' with everybody.
But whatever it is, I really doubt he is rekindling his R with OW1 - if he was, why would he be inviting you to his place next weekend?
So why not spend this week NOT WORRYING about what H is doing. Do for yourself. Live large. And approach next weekend with a beginner's mind. No expectations. High PMA. Look at it as a chance to show H your changes - and let HIM reveal himself to you.
