Business? or Pleasure?

Oh my God, you guys.  I am SO~~ confused.

I have an account with a small bank that has only several branch locations.  They happened to have a branch close to my work, so I’ve been using that branch for 2 1/2 years.

Whenever I go there, I would see this teller lady, I will call her Ms. Moolah.  Ms Moolah is a classy older woman with glasses.  For two and a half years, I have never seen her wearing the same clothes twice. We exchange small talk whenever I see her.  I like her and I find her attractive.  She has to know that I like her.

One day, on my lunch time, I went to the bank for a routine deposit and saw Ms. Moolah standing out in the lobby area.  It was the first time seeing her not sitting behind the counter.  So, I gave her a hug.  She hugged me back.  Then she went back behind the counter to take care of me.  I told her how she was always looking good.  “Good for you” I said.  Then I went back to work.

Three days later, I received a card from the bank.  It was a hand-written card from Ms. Moolah herself.   She also included her business card with her email address.

I am SO~~~ confused.  What do you make out of this?  What should I do?
