Why do men cheat, then beg you to come back?

Anonymous
(just as a disclaimer, I know women cheat also) So recently I ended a relationship with a boyfriend of 3 years because I found out he cheated on me. I did the adult thing and just cut him out of my life. I didn't like mess up his car or cut up his clothes because I'm not a child. Everything was fine for about 3 weeks and I had moved on. About 4 days ago he's started calling and texting me and even emailing me that he wants me back and that he made a mistake. As of today he's already left 14 voicemail messages. I don't know I guess this is like a compound question lol. 1. Why do men cheat and beg for you to come back? 2. What can I do to let this guy know that I want nothing to do with him ever again? Thanks!
