mr ex man rides again

i am not a friend of mr ex man on facebook,myspace,ldslinkup or any other social networking website. i deleted him from all a long time ago. today, out of the blue, i get an email from him via facebook. i was quite stunned, but it truly seemed an answer to a prayer. i have been praying for days for the answers to what to do with this man. continue on without him? we emailed back and forth for a few hours. seemed to be going well, but then.....the blame game. truly. it has to be all my fault for him to be satisfied. he literally blames me for the fact that he called me horrible,ugly names. if i hadnt provoked him....he was only responding to me.....BLAH BLAH BLAH. then he bails from the conversation all together. common tactic. i just dont get it.
