LR, the best thing you can do right now is work on detaching.
We really do understand what it's like to go through the anxiety, the heart wrenching emotions of dealing with a spouse who believes they want to leave us and move on to a life of their own without us...
It is not easy and will take time and you'll have your up and down moments and days... but you need to detach so that you can hold your head up and act with strength and become a man only a fool will leave.
Lonely, you did just fine. You tested the waters and you got good information....and you were NOT rejected. She gave you some positives and you have positive communication in between.
MHL and Kaffe gave you GREAT advice. Be real clear. When you can test again: Or give her 2 options. Does this work for you, or would this be better? If she takes neither, drop it for awhile.
Now---what would have to happen before she would accept a meetup?
