What do we do when we fall off the horse?

I have found that after breaking things off with a girl, I will usually experience a two-week, woe-is-me-i'll-never-find-the-right-girl hangover. But then, out of nowhere I'll find myself right back in the thick of it and not even know what had happened, e.g. today's gmail chat with a former fling.

[idle chit chat about work and school and nothing of consequence leads to...]

CHICK: so what are your weekend plans
CMIKE: i have a wedding tomorrow night. tonight, i'm not sure...probably just sit around, wait for your call
CHICK: too bad i deleted your number
CMIKE: too tempting, huh?
CHICK: so tempting. im joking, i have it, i'm not that big of an ass like you
CMIKE: ow
CHICK: i did delete it though a while back and had to get it from robin to call you for my jewelry, hahaha
CMIKE: wow...the true feelings finally come out
CHICK: haha
CMIKE: i can't believe you really deleted my number. i still have yours
CHICK: i was mad at you - you were such a sketchball!
CMIKE: okay, let it all out...we can never be friends with benefits if you can't get past the pain...
CHICK: very funny. i got past it when i deleted you
CMIKE: so now that we're on that level, maybe when you come over tonight, you could maybe bring a friend with you?
CHICK: sure which one
CMIKE: you choose, i like tall fair skinned girls
CHICK: the complete opposite of me
CMIKE: oh, huh, i didn't notice
