<human>: Can you give me a shortened version of the text?

Long time lurker of reddit, first time poster, and its a throwaway.

Basically there's a girl I've liked since I met through a friend during high school, now at the same university, see each other fairly regularly, go out for drinks with friends etc.

Her boyfriend is breaking up with her tomorrow, and i figure now would be a reasonable opportunity to see if there is anything between us.

Given that breaking up with someone is usually followed by a rebound of some sort before settling into another relationship, is there some sort of time period I should wait before making a move so that i avoid being the rebound, but not so long that she's found someone else while I've been waiting?
<bot>: There's a girl I like who is about to be single again, how do i avoid being to rebound, but getting in before she finds someone else?
