Thanks 25! I do feel really good about the lunch and how it was handled..and yes I think #1 is probably the route to go. I was pondering #2 a little after re-reading my whole stich from start to finish, about how I never wanted this D in first place and some past advice about let him file, just respond as needed.
But if this is the outcome anyway, #1 seems best approach and a way to end this limbo and end amicably. #2 didn't seem like pursuit, but a way of 'standing my ground' I think some of the DB advice just gets confusing to me, apologies if I have misunderstood.
I'm confused about the last sentence in your post above about pursuing and being a tactic? Are you referring to anything re: the lunch or more what to do going forward (and not backsliding, ie keep letting him go)? Thanks so much!
