I got approached by a woman at a bar early morning and tried texting her a couple of hours later but the energy feels different when I did. How can I explore this connection.

Was with a couple of buddies watching football and when they stepped out I had a woman get approach me and we vibed. It felt so good to just hit it off. I was low key checking her out earlier but didn’t think that I could approach her. But she approached me. I’m wished I stayed longer but I’m the youngest guy in the group and couldn’t book a hotel close by so I had to leave early but I got her number. Now struggling to figure out what next to do.
