So how can I do this without being creepy

[Tuuvi]

So a few months ago this girl came into my work looking for one of the managers. She recognized me from a class we had together a while ago and she stopped to talk to me for a little bit. Then last week she added me on facebook and she wrote on my wall and when I replied she wrote back "sweet you remember me etc.".

Lately I haven't had anyone to hang out with because a lot of my friends have moved away or are working a lot so I thought it would be cool to ask her if she wanted to hang out, but then when I got on her facebook to send her a message what I planned to write felt awkward and a little creepy. I've always been a little shy about approaching people and most of the friends I've made over the years approached me first so that's why I'm having trouble with this.

How can I phrase the question without sounding weird?

And yes she's really cute, which is probably another reason why I'm a little nervous about it, but I'm not sure if I want to pursue a relationship at this point; I'm mostly just sick of doing nothing but working and sitting around the house and I figured since she went out of her way to talk to me she might be interested in hanging out.
