girl *almost* has boyfriend. uh oh what do i do!?

hey reddit,

i got a small problem regarding a girl i met last night. i went to a dnb party met her added her on facebook and i anonymously said on askfm that i thought she was the prettiest girl at the party. then she asked who i was so i told her it was me. So she is super happy and i think i sealed the deal so i ask another question, what is the most romantic date one could take you on? she says coffee in good company so i ask her out for coffee. she says, thanks but i almost have a boyfriend. what should i do as next move. i don't want to lose her... please help me reddit :)

thanks in advance,
