I've been talking to this girl for a while now on and off ( both seniors; 18) and it seems like everytime we talk, we have trouble learning about each other below the surface, its kinda like talking to an aunt , and now I'm supposed to go to lunch with here after school this Friday, but the place she wants to eat at closes at 2 and opens back up at 5, I guess what I'm asking is advice for texting better and what kind of tips yall have that could potentially help me take he convo to the next level ( I'm outgoing, but pretty quit, open book)

I guess I'm curious with where her mindset is and if I do have a chance with whether its fwb, relationship, or just sex
