Why do people seek revenge on their ex partners?

Everyday men and women all over the world are experiencing heartbreak others deal with rejection in so many, different ways. But, most ex’s go and do the unthinkable ex-lovers have the right to, live in peace and try to find ways to avoid any contact with the one they used to date. However it doesn’t matter if the man or the woman ended the relationship they still believe that there’s still a chance. But in reality it’s over rather they like or not but there are reasons as to why relationships end. Most relationships end due to “infidelity” or they grow apart most relationships end due to (verbal or physical abuse).

I recently got out of one because my ex was abusive I was surprised that she hasn’t called and begged for me back. It stung a little but I had to do what was right for me but even throughout our relationship it was toxic we had arguments most of everyday and some of it was over nothing. We’re both lawyers we have a busy schedule but her attitude towards me took its toll etc. Last month one of my friends made a website and he posted photos of his ex then wrote untruthful statements about her. She filed a multi-million dollar lawsuit against him and a trial date is set for next September.
