So, I'll give y'all the short breakdown of what happened.

I met a girl online. We hit it off. Went out 4 times. She lost interest. Not sure exactly what happened, but I'd guess it had something to do with me getting invested too quickly, and also not really pushing things forward physically (didn't have sex, didn't really even do second base). Yeah I know, not so smooth. Pretty atypical of me, it was one of those cases where you know what NOT to do, and you do it anyway because this girl is special and all that jazz.. Whoops :p

Fast forward a couple months. I send her an email on the dating site just basically saying something to the effect of "how's life", and she texts me. We have a back-and-forth for a few days. I invite her to this event my friends and I are going to (on the day it's happening), she gives a tentative maybe, asks what time it's at, seems open to the idea of going. I had to cancel out due to friends wanting to do something different. I say we should still grab a drink on Monday, she tells me her work is madness these days and it's hard to make definitive plans on weeknights, but maybe. As I could have predicted, she couldn't make it today, didn't suggest another day/time or anything like that. I'm not getting the impression that she has any investment in this or gives much of a crap.

Not sure exactly how to proceed. I know that she has a negative impression of me due to whatever shitty version of me was on display the last time-and-a-half or so that we hung out. But, I'm kinda past it and cognizant of what I did wrong.. I'm not nearly as invested in this as before, and I honestly think I'd be good-to-go if I saw her in person, but it's just a matter of making that happen. Aaand that's where it gets tricky. I'd like to handle this with extreme caution right now, and would be much obliged if you could provide me with a bit of advice here..

I wish calling people was still socially acceptable in 2013 :p

dude, honestly shes not interested so just move on. find another chick
