How do I ask if she’s interested?

Hello everyone,

I (23 M) just moved to a new city this year, and have been able to find a group of people that I really enjoy hanging out with. I met them through a couple of the guys I knew before I moved, but have been able to get to know everyone else on their own over time. I have a bit of a crush on one of the girls (23 F, we’ll call her E) in the group, and want to ask her out. We were having an Oktoberfest get-together this past weekend, and while we were there, I found out from one of the guys who’s dating E’s best friend that she was single. I was a bit drunk, but later that night I asked E privately if she’d be interested in getting to know each other sometime…at least I think I did. At the very least, she seemed interested, and I did get her number, but I don’t remember the exact language I used. I do remember walking E to her bus stop, but I don’t know if I was being too vague, or if she actually was interested. So far she just thanked me for walking her to the stop, and I said “No Problem”, but I haven’t said anything since. What would you say the best way to go about broaching the topic would be?
