So college finishes for the summer next week and I need to act fast (tomorrow or the day after).
I randomly asked a girl if she wanted to grab coffee sometime a few weeks ago (I'd seen her around campus). I left my number with her. She text me the next day saying sure, and after cancelling due to an appointment she'd forgotten about, we met for coffee that saturday night. It was awesome, we both laughed and talked for nearly 3 hours. A couple of days later she sends me a text out of nowhere saying that she'd had fun and she'd like to hangout again sometime. I said definitely, and asked if that Thursday worked, and she said yes. I text her the day before we'd planned to hangout to confirm the date, but she said that a lot of work had come up for her classes and she was going to be busy. I said 'that's fine, let me know when you're free to hangout'.
I texted her on saturday morning (i know, i know i shouldn't have...mistake on my part) asking if she wanted to get dinner that night, but she said she'd already had plans for a girl's night and was going to eat with her roommate. I made a joke about her being so busy and we haven't talked since.
The semester ends next week so I need to act fast. I know I've messed up a lot here, but I honestly don't know what to do - completely confused. Help please?
