So I messaged this girl on Instagram that I've known since high school. I'm now 24 and so is she and we have known of each other for a while. We had a good conversation for about an hour, then I asked her if she had plans this weekend, which she replied I'm working all weekend :/ . I then said ahh okay, well text me and maybe we can do dinner when you're off work. I then left my number with a smiley face emoji. She then liked/hearted what I had said, but I haven't heard from her since. That was yesterday. Any suggestions of what to do next? Messege her again in a few days?
