...... I have no idea where they are now.
It is simply a matter of time before they move on for one reason or another. That's why when you find someone you really enjoy, you should give her your (throw away) cell number and name (the name that you told her you are anyway) and tell her to call you if she goes to another place.
BTW - I say " I really like seeing you - if you ever go to another place please call me and I will see you there"
A benefit of such a line is that
every time I have used it my level of extras went up and the GFE factor also went up.
My tracfone cost me $15 to buy and maybe I spend $60 a year on minutes. No brainer.
Also - if you get to the point where you want someone new (as just about every guy does periodically) you change her name in your contacts to "dontansw" - for multiples use dontanswA, dontanswB, etc. This also works if she tries to call you every time she isn't busy - only happened to me once.
