How to let married women know I'm interested?

So, I have gotten really close with this girl who's only few years older than me in school. We really have fun talking to each other, making jokes and what not. I don't wanna make a move and embarrass because she's married, and I respect the fact that she is.But how can I let her know politely that I am/will be on her if she's ever single in future? :(

Put the internet to work for you.
