there's a girl that i have a crush,on the last day of school i sum up the courage to talk to her.We had a really cool conversation we had the same interest in anime music and some other stuff. she seemed like the perfect girl for me,i ended up getting her aim and phone number. but there's one huge problem my friend told me she has a boyfriend,they have been dating for atleast 2 months!!!

my only options seem to be
1.talk to her and build our relationship
2.wait to summer break is over to see her again
3.confront her and risk everything by asking her out
4.wait and hope they break up

please help with some advice
