Wow. simply surprised. After reading this whole thread I realized i was in the same exact situation for the last while. literally same exact thing (only instead of work; school, and instead of bars; just hangin out/whatnot). but seriously bro, one-itis much? i mean i am no pua, but i think its a little too late to go back. you have already put in so much effort into this girl that she wasn't worth, and now you are putting in more. just end it and move on go for other girls out there you will feel a lot better for it. she doesn't deserve you having disrespected you like that, and it seems like you guys have awkward situations after everything you have been through, why waste more time?
but this thread also helped me understand what I went through, and i wish i had taken a lot of the advice that was offered because i am sure it would have worked. but seriously dude.. move on.. theres countless fish in that sea.. just learn from your mistakes and use the (im the prize, not the option) mentality in the future.
P.S. -in my case i actually got laid though,

, but only thanks to a little liquid friend of mine hehe.
