<human>: Can you summarize the given text in a few sentences?

At the start of the month I [18M] went to a party with a girl [19] I like from university, we've only briefly chatted before this, but spent most of the time chatting to each other and getting very drunk just the two of us despite the party. From what I remember afterwards she dragged me back to my room, we made sure we were both okay (relatively speaking) and then went our seperate ways. A few days (4/5) later as I was travelling home for christmas I messaged her about the night - working out what went on etc. as I couldn't remember a couple details and we had a great long funny conversation which quickly moved on from the nights events to other things.

I left it a few more days and messaged her "Hey! How are you?" and didn't get a response, at all but she didn't see the message until a couple days after it was sent.

So my issue boils down to this, do I message her again asking how her christmas was as a way to develop the friendship to the point where I can just ask her out, wait until i go back to uni in around 10 days where I will bump into her and see her anyway (We live in the same accomodation) or is she simply not interested and I should give up and move on?

Any help would be appreciated I am genuinely useless at this whole thing, the last couplr girls i've been into i've either sunk too much time into them when they are uninterested or not made the move when i should have and left it too late.
<bot>: Had a few good conversations with a girl but didnt get a reply, do I message her again, wait till I see her in person soon or give up?
