My ex-boyfriend broke up with me. When I have already moved on, he keeps on messaging me on facebook (I unfriended him already but did not block. he might think i'm bitter if I blocked him) that he broke up with me because I have a third party (which is not true. it's the other way around. actually he broke up with me because he has a new girlfriend.) So I just ignored him and moved on. When they broke up, he messages me again asking if I'm still mad at him. I just keep on ignoring him. If I lose my temper, I am going to block him.
