Left on read after re engaging

Probably a time waster. You did pretty well actually

You think she was investing but she was not. She was just seeing where things are going

Yeah man, this is way too sexual for cold Instagram DM's in my opinion. She's 17, so she's much more likely to get freaked out in additiopn. I recommend toning down the gaminess. It's much better to just have a normal conversation rather then try to be fancy and whatnot. Theirs a good chance this chick might be a virgin due to her age. So going explicitly sexual is even less recommended here.
