Breh, just stop. If a chick wanna be with you, let HER bring it up. I got into some shyt like this twice with these two chicks and once everything was all said and done, I should've kept my mouth shut and just kept it the way it was.
On the other hand, this other chick I used to talk to was just like you(Asking "what are we?" "What do you want from me??") and I, just like the girl in your story was beating around the bush. In reality, I liked her but not LIKE THAT. I mean I just wanted to fukk and have someone come over to chill once in a while but I wasn't really tryna get serious with her. Truthfully, I was still smashin this other chick. So imo, I think ole girl in the OP not fully invested into you because she still probably fukkin with someone else or she's talking to someone else or something.
