ODD BEHAVIOR FROM A MAN? Why did he ask him that if he doesn’t give a fuck?

Anonymous
i use to mess around with this guy and he’s been seeing me with my guy best friend QUITE A BIT lately and he asked one of his friends who knows MY guy friend about me and MY guy friend.

the guy has been seeing me and my guy friend hanging out the past three days straight and watches us and stares. Lied to me about seeing me with him but I have MULTIPLE witnesses telling me he was watching us hang out together and even told his guy friend to “move over” so he could see us better. All his friends even keep looking at me and my guy friend.

*here’s the conversation* *D is the guy and J is HIS guy friend*
D: does G still work there?
J: yeah, he’s one of the managers
D: are A & G dating?
J: I don’t know man, it isn’t any of my business

the guy told me he didn’t give a fuck about me and he never did but why did he ask his guy friend if i’m dating the dude he had problems with while me and him were together?
