Search Results: how to act around a crush

I work a job that's installs and repair, and I frequently visit one location for the company, that I used to be a regular retail employee at last year. I had a huge crush on a girl that works there, and at first it seemed mutual because a few co-workers commented on the conversations we'd have.
I backed off because she got a boyfriend and she was underage, but she'd come ask me advice or act strangely at times.
Anyway, now when I visit her location, I will often catch her looking at me as I walk around, and one time she came up to me, said hi, but became super giggly and walked away. But last week she kept getting in my way as I was leaving so she could say hi to me, and she acts funny when I'm around. But as far as I know she has a boyfriend still.
