Run! Stop! Run! Stop! Then run like hell!
Plain and simple, play hard to get. If she decides she wants you she'll come back to you time & time again.
This puts you in a very important position. You are in control of what happens with the relationship. Make her prove that she loves you. If she does, then you have a decision to make. If she never comes back, then you were still in control and you didn't waste time chasing her while she got her emotions in check (shouldn’t take long). Meanwhile, she’ll be simultaneously getting her ass out the door w/ her girlfriends for nights of drunken margarita debauchery, ass shaking and dry humping, free drinks receiving from no game having Lee Hotti wanna bees prowling on the town 3 days a week. Sounds harsh, I know…
Shit, give her some space. Give her MORE than what she asked for. You get your ass out the door as well. Go party with your buddies and have a grand ol' time 4 times a week.
Seriously! Trust me on this! I just went through this a few weeks ago.
Don't be a jackass to her though, be really nice to her when you bump into her or she calls you. Just remember: "gee, I'm sorry, but I'm going out with the guys tonight. We've been planning this for days. I'll have to check my schedule, but maybe next week though. Call me later though, peace".
