Break Up & Divorce

My ex kept looking my way at a party? Does it means something? Please read the situation below and give me some helpful opinion if you have time :) ?

Two days ago I was at this party and I ran into my ex. He kept looking my way, turning around, acting quite nervous but he never really looked me in the eyes. I mean yes we did make eye contact but it was just for a second. Once my friends sat on these sofas and they were next to where he was sitting... I was among guys and he looked sooo uncomfortable, again looking my way, but never truly looking if you know what I mean.
What do you think about this situation? Does he still have feelings? I'm curious about this because when I have no feelings towards someone I totally turn them off and ignore them. Thank you for your help in advance. Xoxo
