Why Do Some People Seem to \" Get Off \" on being Cruel ?

 I'm doing My Best to " Move On ", but My EXBF doesn't seem to want to LET ME, I don't think ! WHY ELSE would He keep surprising Me from Time to Time, CALLING ME... when He made it Clear a while back that I'M NEVER SUPPOSED TO CALL HIM AGAIN !!!! Is that Messed Up, or What ??!!! I don't want to be the " BAD GUY " - so to speak, and suddenly STOP accepting His Calls.... BUT He's forcing Me to think about doing that ! HOW Else am I going to be able to completely Heal from the Pain, and Heart Break, that He put Me through, IF I keep hearing from Him !??!!?!I had Thought at First that Him and I could at Least still be FRIENDS, but I'm thinking now that that probably would NOT be such a Good Thing. Being Friends with My EXBF would just leave Me OPEN to Him still Playing with My Heart, and Soul, whenever He wanted to !Supposedly He had recently told My Old High School Friend that He wants Me to " Move On, and Forget About Me "...  Oh Really ??? IF that was what He TRULY felt, then WHY does He CONTINUE to CALL ME ?!I've been Enjoying FREEDOM from FEAR, without My EXBF here, but now I need Him to LIVE BY HIS OWN WORDS... AND TO STOP CALLING ME !!!!Then when He TRULY STOPS CALLING ME.... THEN I can be Completely FREE to continue to Move On, and let My Heart Heal from all the Pain, Misery, and Heart Break, He caused in My Life ! It was BAD ENOUGH that MY EXBF ABUSED ME for so Long... Emotionally, and Physically... BUT NOW when We're supposed to be OVER... to continue to TORMENT ME, is just PURE CRUELTY ! It's Cruelty that is almost beyond Words to describe !
