There's this girl who I talk to and we make very small talk the conversations don't last long at all. I am not sure if she likes me but she will say "hey" and "what's up" so she at least doesn't mind talking to me. I only see her where she works at a fitness center. I want to get her number (which I could use help with) but also get to know her better? I'm also debating on if I should send her a friend request on Facebook. This has been going on for about a month now, but we have known who each other is for about 4-5 months, but are talking more now.
