Hello u2fan and welcome to a2k
It looks like you're both shy and each one is waiting for the other to make
the first move. Well, u2, she took already the initiative when you were leaving
the pub and she took you to a house party. She also answers your text messages
which is giving you plenty of hints that she is interested. Your next move
would be to call her (not texting) and ask her for a date. I am certain she
will accept - have fun u 2 !
