Does he like me? (10 points for relevant honesty)?

We're in the same program AFJROTC together. We're 16 in high school. Up until a couple days ago, we texted just about every day from around 6 until one of us (usually him) falls asleep. We flirt playfully with each other over text, and I wait until he texts me first 3/4 times. I asked if he wanted to hang out this week and since I hate decisions he said he'd think, and invited me to a movie or his house for a movie, and we picked his house (not that we'd do anything like that, yet :P). Before he's said I was the first girl he knew who liked horror movies and that he was happy our astrological signs were compatible. Then something came up and he's been acting different and not really talking to me and said something came up in his family. I said I respected that and hoped that everything would be alright. We haven't really talked since, but he's constantly been on Facebook and made plans with these guys to play handball today, when we were originally going to hang out. Do I go onto the next one or? I really like him. Thanks for reading and answering.
