Scorpio Stare- quick story and question

Whats it about? How come there's no wave or anything to start communication? I had a fall out with an ex and we haven't talked in long time. Now when I see him in passing he always stares at me but when I look in his direction hell put his head down but the moment I look away he turns and glances and stares at me. I assume when he puts his head down he doesn't want to talk or me to see him so then I'm just like whatever and I look on. No dirty looks or anything. Sometimes he'll even smile to himself when he looks at me. So then I just think he's talking butter in his head lol. But I don't know it's confusing. When we were together he used to stare at me a lot but we were together then and he never put his head down like he does now. Any thoughts?

There is a chance he might think I still dislike him lol if that matters at all but I have no hard feelings towards him anymore. I just go about my business now.

We can be as cold as Mr.Freeze after a breakup. Just talk to him. Ask him what's up?

I woukd think if he's looking at you at all is a good sign. If Scorpios want nothing to do with you they will pretend you don't exist. And they are good at it look at the Mr. Freeze comment.
