I think you are doing really well B... in the beginning you were in 'what's she thinking' full mode but I can see that you're changing. So give yourself a pat, if you're too hard on yourself the negative cycle will bite you (remember the white dog)
It's true what you said, it's the moment that you miss and not the place. And I tend to make the past more beautiful in memory than how it actually was. Puts it all in perspective... I will remind myself of that.
I talked to someone who knows both of us quite well and was advised to move on... it's just unhealthy. So I'm thinking of nc all the way. After all, you can lead a horse to water, but you can't make it drink.
