Be careful what you wish for...and I think many of us wish it, that those we left behind or who left us behind will not get over it and recognize that we were the best person for them in their life.
My exabf feels that way, and it makes me sad for him. I have moved on and married, but as long as he feels this way and his new dates and girlfriends know it he will never be able to love them right and his relationships are doomed. He is the one who needs to let go now.
So in the end, that isn't satisfying, it is very sad.
It's nice to hear thank you, I learned so much from you and you were good for me.
But don't pine for me or compare other women to me. We had what we had and it is long past.
