I met this girl... is she worth pursuing?

ok i meet this girl at this party. we get along pretty well and by the end of the night we are pretty drunk and we hook up. this girl is hot and had been planning to get with me the entire night (weird but ok). so the next day i check my mail and she friend requests on FB right away. so i talk to my other friend who kind of knows her and he tells me that shes pretty popular with the guys. then she IMs me and we talk about all this stupid **** tht happened at the party. i dont plan on IMing her back anytime soon but she might idk. so what should i do? is she worth to pursue? i dont think she is but im lookin for some opinions. i might invite her to my friends party this weekend, but im not sure. thanks!
