BACKSTORY: So I picked up a girl at a party and had a day 2 right before we went on holiday from class for a month. Kept up conversation over break - just light, fun convo.
Last night was our first night back, and she has never initiated a conversation but last night texted me to see if I was going to a specific party. She showed up a little after I did and we briefly talked, but I was busy talking with some other people and she kept disappearing and what not. When she left once I sent her a text saying
ME: "You too tired from partying already? I mean I know its ur first day back and all

"
Her: "Haha good joke"
ME: "I wasn't joking"
The whole night was full of brief run ins but nothing really because I didn't feel like chasing after her and some guy was hitting on her the entire night. Which he had actually said something to me because he found out that i was into her, and I told him that he was free to have his go at her. To sum up, I know she was upset about something at the end of the night, not sure about what though.
Should I be trying to do damage control? And either way, how can I keep things moving forward with her?
Thanks,
