<human>: Can you condense the text into a few key points?

15M. There are about 10 of us in our social circle, and the girl (we'll call her 'S.') I've liked for a while broke up with her boyfriend recently. He wasn't part of our circle, and he was a total jerk to her. He didn't get her anything for Valentine's Day, and when he broke up with her, he had her bestfriend do it for him, but I digress.

I would like to ask her out (most likely not for a while because they just broke up), my guy friends think I should ask her out, but I don't know how she feels. Another problem is another guy in our group thought he loved her, and he told me and a girl in our group about a month ago. About 2-3 weeks later, he supposedly got over her. My questions are:

1. Should I ask her out in the first place?* We're friends, but my relationship with her is different than my other [girl]friends; I wouldn't go to her for advice with a girl if I needed any.
* If I should ask her out, how long should I wait? Would asking her to hang out over the weekend be okay, and after a while ask her on a date?
* My friend may have feelings for her again now that her boyfriend broke up with her. He is my friend, and I wouldn't want to hurt him. I asked a friend, and he said to just go for her anyway, and to not worry about him.
* And finally, should I ask her bestfriend to help me. I trust her enough not to say anything, but I'm not sure if I should ask her or not. Maybe having my friend say something about S. and I to her bestfriend is the best option?
<bot>: I like a girl in my social circle. She just got out of a bad relationship, plus my friend *thought he loved her*, and I'm not sure if he truly doesn't anymore.
