After your crush breaks up with her boyfriend should you immediatly ask her out?

Wait some days but not too long, so she won't think that you are just another one of those guys that will dump her soon, if she seems fine. If she seems hurts, wait till she's better, and until that give her moral support. Also if you know her a little try to comfort her only if she is hurt,AND IF YOU DO ASK HER OUT TRY NOT MENTION HER OLD BOYFRIEND UNLESS SHE MENTIONS HIM.
