my ex said he wants nothing to do with me

Cleaned and corrected English version:

My ex and I always had a very difficult relationship, and I would say that we both have strong tempers. Yesterday, I texted him asking if we could be friends, and he simply said no. The day before, we had another argument. It has been like this for several months, even though we officially broke up in March. During that argument (the one yesterday), he said some really horrible things to me. He joked that I was nothing more than a sex toy, that he would never respect me, that any effort he put into our relationship felt like a waste of energy, that he didn't like me anymore, and that I was nothing but a piece of meat in his eyes. The list goes on. I don't understand why I can't move on. Why does he seem to only want me sexually? I know I can be very clingy and annoying, and I want attention all the time, but hearing things like this from someone you love unconditionally is incredibly jarring. What can I do to move on and forgive him? How do I stop wishing he was the person he used to be? I don't know anything anymore.
