Last thursday I had to take a trainride during the day. Didn't see anyone to sarge on the platform, so didn't open anyone and entered the train. First seat I see a blonde HB8, so instead of moving to further seats I place my briefcase over her head and sit down across from her.
Just then she puts down the paper and I go "so, what's new in the world?"
She replies and we talk for the whole train ride (25min). At the end I say we should meet up and she gives me her phone number.
Two days later I text her we should go have a drink and give her two days to choose from.
She replies a few hours later that she's only available on day two, but wants to meet.
Two days after that she texts if i can meet up that night, since she can't make the promised day two. I wait a bit and reply to meet up. She replies "ok

Cya then!"
Only an hour later I get a looong text in which she says she's gotta be honest and that she has a boyfriend. She wanted to meet up to get to know me as friends but after talking it over with her BF she says she understands his argument and also thinks it's not a good idea. She apologizes too.
So I just reply it was nice meeting her and that it's no problem.
Then she replies it was fun to meet me too and asks if i have facebook. I go yeah and ten minutes later she adds me.
That's the story so far. Failed PU, but I wonder if I could move on from here with this girl? I didn't make big mistakes yet, she's in comfort with me and I haven't been AFC/insulting of her BF.
