Break up move on

My bf broke up with me check my profile for deberied - was nice then had a convo with his friend the next day and turned so disrespectful we ended on good terms and as friends and he stood infront of me to take me out of a group conversation at a birthday and wouldn’t smile r do anything when I smiled but what’s to end on good terms and be friends ? I want a convo for closure he said “I fully understand but idk like I’m trying to move on I’ve nothing to say if we do meet up like we r jist gna b upset and probably crying” i said it’s okay to cry we r both hurt but it would help me big time in simple terms. He mentioned abt maybe in the future - what do I do will no contact get him back or is he done fr fr (been best friends for 2 years and then went out for 4 years )
