Hi BG- It certainly does sound like your W is warming up some, that she is missing you, and that she is thinking quite a bit about the wonderful times that you shared. I would not press the Retrovaille issue now, but I think it might be o.k. to ask her to do something with you that the two of you always enjoyed. Keep it light and let her see further all that she is missing. How about a comedy club night in Boston or something that would further bring out her smile. How about getting ahold of some tickets for "Nutcracker" and extending an invite. Be prepared for her to decline and do not initiate any OR conversations, regardless of whether she accepts or not. Resist the temptation to explain that the evening has no strings attached and just be very matter of fact about it.
I'll be looking forward to see what you think of inviting her out. Keep the positive mental attitude--Jamie
