why did he ever marry me?

my stbx tells me that when we were 2gether he wld look at other couples with disdain.  i feel like he betrayed me from the moment we took our vows.  that he was not committed to keeping those vows.  that he just thought/hoped hed want to.  hoped that a good marriage would happen and had no intention to do anything to make sure that a good marriage would happen.  and he took me along for the hellbound ride. 
ive been talking to hm out of lonliness.  out of hope.  out of familiarity.  but really.  really.  i dont wanna b his friend.  he is not worthy of my friendship.  i dont know if hes a good person bad person...i dont care. 
he's not been good 2 me.
other than idle chatter and occassional service.  helping me move furniture. what is he really offering to my life?
its hard 2 let go.  i guess im doing it gradually.  but i cant talk to him about a guy and i cant have him talking to me about some chick.  and we are both intellectual people and we have good convos that way....i kinda want him out of my lfe.
right now im so angry.  our friendship is one sided. 
we r not friends.  i dont know what our relationship is
i need some distance and a break
2day i kinda hate him
