The past resurfacing

For those of you who come across this part of the Masterpiece, beware: inner thoughts and emotions may surface.

So I was at Anna's last week...
What am I supposed to do with this? I don't have a lot of experience dealing with relationships, but I've come across a new thought. New for me, anyway. She broke up with me. So what is the dump-ee supposed to do with their feelings? A dump-er has obviously made the decision to move on, but all the things she was when we were together...she's still all those things. Am I not supposed to like her? I mean yeah it's been over three years, but when you come across someone who has an attractive personality/etc., you like them. And like I said she's still all the things I loved. So what am I supposed to do with those kind of emotions? Had we just met, I'd ask her out or something. But, ya know, what the heck? Any suggestions?
