A few days ago I matched with a girl on tinder who I've known since high school (I'm 22, she is 20). We've been friendly but haven't specifically kept in touch. We're both musicians (although I'm a professional musician and she majored in something else) and we both coincidentally got hired for the same gig tomorrow. She asked if I was driving, because she is "still a terrible driver". So I told her to meet me at my house tomorrow and drive up with me, which is what we're doing.

Basically I have an hour and a half drive up, like 3 hours for the gig, and then a drive back. To be perfectly honest, I am really nervous as this is a lot of time to spend with her in one day. I could see me and her dating, but I don't want to be presumptuous about the whole thing. her matching with me on tinder and wanting to drive up to this thing with me might seem like a good sign, but I wouldn't be surprised if she turned around and just friendzoned the shit out of me.

Any advice? Haven't had a girlfriend of any sort for 2 years.
