How to deal with impossible love?

This may sound weird but its true.

I went to the bank last week to open an account and then i meet the most beautiful woman i've ever seen.

And i fall in love hehe

Well, she works at the bank, but i feel nervous to go back there and ask her to go out.

First because, i don't know if she's alredy taken, second, she would call me crazy or what?

Why is it impossible? Surely you can find something else she can help you with... a new account, on-line banking, etc.

After speaking with her a couple of times, you should be able to discover whether she is involved or even if she's interested.

Go, what's the worse that she can say? No? Then you're in the same place you were before, so you only have her to gain by going and nothing to lose.
Are you in love with the woman or her beauty? You can go back to the bank introduce yourself, (let her know how you know her, in case she doesn't remember you), and ask her what her status is and tell her why you're asking that. If she's single and not involved with anyone, then ask her out on a non-personal date for a friendly talk. I don't think she would call you crazy, she'll just think you want to ask her out. Be polite, friendly, and serious all at the same time when approaching her. If she declines your invitation, then at least you tried. You will not have to keep wondering and thinking about asking her out. Remember, inner beauty is far more important than outer beauty.
