"I'll never forgive you as long as I live!" I shouted at Candy.  She just smirked at me as if she could care less if she were in my good graces or not.
"My children already hate you!" I yelled again, trying to find anything to break her triumphant attitude.
"He will just cheat on you too.  He cheated on me twice."  There, a flinch.  I found her area of doubt.  How do I capitalize on this and make her squirm and hurt as much as I do?
"I bet he plays his ukulele and sings you songs.  Those are the only songs he knows and he sings them to whomever his current love interest is."  Now I smirk as I see her smile falter. 
"I told you from the beginning that you are just a number in his long list of conquests.  He is not capable of loving anyone but himself."  There must have been a ring of truth because she scowled at me.
"It's alright, it's alright."  I placate with sarcasm.  
"He will tire of you and move on to someone else he sees can advance his career or his image and need for admiration."  She stares daggers because she has yet to master the english language.  I am sure she is thinking some really horrible Russian curses right now, but uttering them will just sound like gibberish to me so she remains silent and hostile.
