so my ex broke up with me a few months ago and we haven't contacted each other at all since then. Not even on holidays or birthdays. I have been on no contact ever since. We haven't deleted each other off of social media. the thing is that I have stopped watching his Snapchat stories ever since the break up but he watches every single one mine till the very end. he is usually the first ones to watch them. when I went on a trip, I used to post 100s of snaps in a day and he would watch them all in one go. We don't see each other's faces at college and pass by the other as if we are strangers. I have caught him staring at me quite a few times as well. Does this mean anything or am I thinking too much?
