<human>: Can you give me a shortened version of the text?

I've never really been a relationship person - dated 3 girls total, none of which lasted for more than a few weeks. Essentially, I'm brand new at this and have no idea what I'm doing, but with starting college I want to start getting out more as well.

Earlier this week, I asked a girl in my Japanese class out to dinner. We had some common interests (music), she's attractive, and we got along pretty well. She said yes, so score! It's a date!

Except tonight... I'm pretty sure it wasn't a date. I think she thought it was just going out to get some food, while I was thinking it was a date. To start off with I showed up wearing at least a little nicer clothes than normal (collared shirt, nicer pants). She was just wearing her normal clothes from school. We talked throughout dinner, I thought it was a good time. Afterwards she said she needed to go clean up her apartment since she had people from her dance class coming over, so we headed our separate ways.

Overall while it was fun, I definitely got the impression it was less "date" than "eating dinner with a friend". Is that it then? Do I give up and move on to the (non-existent) other girl I'm interested in?

Also, what do I do to make sure everything is clear in the future? Do I have to specify that it's a date? I think my exact wording was something along the lines of "would you like to go get dinner on Friday", so I suppose I see how that could be taken different ways.
<bot>: Went on a date, I don't think it was actually a date. Where did I go wrong, what do I do next, and how do I avoid this in the future?
