Why would a "man" want his ex girlfriend life miserable?

If he has a baby on a way and dumped you and basically with someone else years ago. The ex girlfriend tried to just speak out and say hi to him in a friendly manner. Like why would an ex want to make your life miserable through other people? I am not friends with him but I recently had to work with one of The EX's relatives and a lot horrible things happen to me.
