i agree...women suck...which is why all my friends are men...but men do the same shit...
girl #1 probably got back with her ex on that trip...and if shes moving away...why waste your time???
girl #2 maybe she wants to make sure you're willing to put in the effort...my friend nick's new girl did the same crap to him for like 3 weeks...now they're together...if you feel this chick is worth the trouble...then keep it up and just tell her what you want and maybe she;ll come around...
or just tell both chicks to step up or buh bye.
