Recently I met a girl through Tinder. After talking for a while I asked her out, she said she would be down so I asked for her phone number and she gave me her snapchat instead. I'm pretty new to snapchat and haven't really talked to anyone on there. It doesn't feel right having a full conversation on there, and I'm not really sure what to send her. She often sends me selfies but she doesn't talk much. I reply with a selfie of my own, say things like "Good morning" but that's about it. I've tried asking her out once more but she gave me the "busy" answer, which sorta makes me think I'm in rejection territory, although she's still sending me snaps. I know I could be doing more but not sure what to do. Any thoughts?
