I remember that situation... I guess its good not to see you around, that means all is well, that or you're not like me... bored out of your mind at work sometimes.

I would tell your current girlfriend... Wouldn't you like to know if the shoe was on the other foot? Besides, things always have a way of comming back around, and if you didn't mention it, it would infer that you had something to hide...

I think it would be good for you two to meet up. Just remember what she did to you. See her as her now, not the way you have her in your memory (Where she can do no harm).
I wish you luck, and to find your peace.
