Being cheated on is one of the worst feelings ever. Unfortunately, if it happens to you, it leaves a scar that stays almost forever. And even if you heal from it, you can’t even bear to see someone else cheat on anyone, especially if it’s someone in your own family.
Even the original poster (OP) of this story had been cheated on in the past and when he saw his own son do the exact same thing to his pregnant girlfriend, he went and told her. Well, she broke off things and aborted the baby, sparking his family’s fury against him.
