What does it mean when a guy avoids you?

A guy acts he likes me and it appear so clearly to me after I ingore him or I give him many mixed signs and all his friends know and they stare at me whatever they see me but he ingores me completely and talk with any girl and follow her account expect me and he makes me jealous a lot and hurt me

And he says (we were in a realationship! And he still loves me) we never talk! He didn't make any move and he didn't tell the turth why he doesn't talk with me?

And I see his friends avoids me too and some of them blocked me.

I don't understand anything and this hurts me so bad
