For a while now I have been applying some of the stuff I've found here and several other sources. They all give very specific advice on how to get women, but I see a lack of information regardig what to do afterwards.

I had sex with a girl which happens to be a very close friend to a female friend of mine. For the past 3 days she's been texting me, calling me and fb be all day and i want her to stop.

How can I make her stop without coming out like a jerk to her and my friend?
