Now I’m a problem because my ex boyfriend want me back because his girlfriend had dumped him.I feel so sorry for him, please help me!

My ex boyfriend and I were on good terms and I was in his life. He doesn’t want to see anyone else, but he doesn’t want a relationship either. I stopped talking to him a couple weeks ago, thinking he’ll miss me and want a relationship. Am I doing the right thing by not talking to him and giving him zero attention? I need advice on what to do to get him back. What will make him want to pursue a relationship again with me? What makes guys want someone?

My ex boyfriend is a jerk and always lied to me, how do i get back at him?
