<human>: To briefly explain the breakup, we never had great communication and were together for a 2 years but he never got along that well with my family, among other issues. He would constantly take out his anger and frustrations on me so I decided to end things to try to get myself out of the situation. 

That's where everything went from bad to worse. He started texting me, begging me to get back together. Then he began calling me throughout the day several times in a row. He sent me Facebook messages, emails, spammed my instagram photos with comments. You name it and he did it. I blocked him on all social media and then he started calling members of my family. He called my dad, my mom, my house phone. He would text them repeatedly and eventually, I decided to add him back on social media so that my family could stop being harassed. 

Now I'm at a point where I can't take it anymore. What can I say to him to make him realize that I'm not ever going to think getting back together is a good idea? I want to handle the situation delicately so to not make him more furious like he has been in the past.

Provide a brief overview of the text.
