I have still going on a situation like this.
Two beautiful girls, actually all girls of their group are beautiful
I went out with one of them I was not interested in as friends and talked about what ever. But what happened was that she told the other girls about our date and that I'm such a great guy and blahblah...
Now I'm just flirting with both of them and actually I wait which one of them will get a chance when we meet at a club or wherever...
I'm not investing much at all...I can't even decide which one of them I like more so I don't ask either one of them out because that would ruin my chances with the other one. So let's see what happens while I'm gaming a bunch of other girls meanwhile^^
