I have ran into my ex boyfriend and every time I do he hangs his head down and or walks the opposite direction. Once he held the door open for me when we ran into each other at a store. I said thank you but he didn't say anything back. I was told him hanging his head is because he doesn’t want me talking to him. I haven’t even tried talking to him. Is it this or he literally can’t look at me? FYI: he broke up with me and bad thing after the break up. We have not tried talking. Just curious why, if he is so over me, would he hang his head when he sees me?
