First of all, you didn't sarge the lesser of the two, you sarged the hb 7. So don't lose your focus and don't worry about the friend. Keep it light with her friend, but don't actually text or message anything that would give her the idea your interested. Talk to her about things like, " what are you doing this weekend?" or like lyric says invite them both out to do something, but still focus on hb 7 to get a better feel of where your at. As for the one night stand, mystery says it takes a cumulative time (whether it be talking on the phone/texting/facebook messaging) of about 7 hours before a girl is ready to sleep with you, and i gotta say that average is pretty accurate. Now you get better at it, but once you get what you want you can just go out the next night and sarge again. Don't sweat the girls, tell her you had fun and slowly talk to her less and less after. She texts don't text back, or maybe just text once a day, eventually they'll get tired of texting and you've all ready got another one lined up

hope this helps
