Ok so there is this guy I have known from school we didn't hang around or anything with each other just due to being in diff years. But if we saw each other we would say hi and sometimes talked. But he is friendly to everyone. I hanged out with him a few years past at a party and we spend most of the night talking to each other but nothing happend. That was 2 years ago. Anyway he follows me on all social media sites and just recently we started talking again. He usually messages me when he is drunk. Or at nighttime. He keeps on saying we need to meet up for drinks and getting into all sorts of trouble and we have been flirting a bit through messages. But he have t messaged me for the last week and when I messaged him he never replied. Why he going all cold. So confused.
