<human>: Give me the gist of the text in a nutshell

A bit of background: I used to be very obese and self-loathing. I pretty much never went out, other than for work, and thought no one would want me. I've tried to change my ways since then and have gotten down to a normal weight and have kept to it for a year and a half now so I thought it was time I finally asked someone out.

I found out one of my old co-workers, from about 3 years ago who I came along with really well at the time, had been single for a while. I added her on Facebook, chatted with her for an hour or so and then asked if she'd like to go out with me some day.

From the short conversation we had I got that she works a lot. About 9.5 hours a day for 4-5 days a week as a waitress. She replied to my question by saying: "I'll see which days I have off from work. I'll let you know later." It was kind of vague but her first language isn't Finnish like mine is. Definitely sounded more like: I'll go out with you, just don't know which day yet.

It's been two days since then and I'm sure she's just been busy with work but I really want to chat with her without it seeming like I'm trying to push for the date to happen or sounding needy. How can I do that or should I just wait and see if she replies? This is all new to me so any help is appreciated.
<bot>: Finally asked a girl out, got a response, haven't heard from her in a couple of days. Should I talk to her or just wait?
