A couple of months a go I met a very hot girl at a party. Gorgeous boobs.
She was speaking the whole time with these other 3 people: a very big silent masculine guy and other two girls who clearly liked him.
At the moment, because I was trying to kickstart my pick-up/dating life I was just naturally playing the entertaining guy (which I am now decreasing, or better, trying to convert it into a more cocky/provocative/dark/sensual kind of humour).
All of a sudden this girls turns her attention to me COMPLETELY. I foolishly assume I've beaten the big Alpha Male with my entertaining skills and she was mine. When I was going away she actually asks: oh wait are you going in the direction of the station? to which I replied yes, to which she said "Ah cool, I am coming with you then".
We lose the bus and I ask her: hey while we wait the next one (10 minutes) why don't we have a fast coffee at this bar? She says yes. She keeps being incredibly warm and open, although she often stares outside of the window (now I know it wasn't because of the bus but because she wanted that other guy to accidentally walk in front of the bar and see her flirting with me). She gives me her number.
Anyway, the moment we take the bus and she looks around to check if that guy was there and finds out he isn't, her warmth suddenly decreases. She had agreed to meet the day after. So I text her. "No I am not feeling energetic". I ask her if she wants to go partying during the WE, she also says she has other things to do. Then the next week, again warmly and enthusiastically she asks "Hey how you doing? why don't you come to this home party I am organizing etc. etc."
That was the moment I got enlightened. I said to myself: "Damn, she's been using me all along and I have been allowing it like the fool that I am". So I said: no I can't, but we can go drinking something later on this week. Never heard from her again.
Right now, when I meet a new girl I already automatically assume there is a possibility she currently has a boyfriend or there is guy she's into and that she might use me. I try to interpret what she says differently, to understand whether she's actually interested or whether she's playing me. Also sometimes they play with you even if they don't have any guy to make jealous. Just for the heck of it.
Another big lesson was: firm, silent, masculine guy much more effective than entertainer.
