Before you say it, I know I got what I deserved because I called.
No rose abuse is never what you deserve. you called because you are compassionate. he abused you because he is abusive. yes it is best if you don't call him because he is a waste of your concern. be kind to yourself he won't
But it really hurts that I have to let go of this 'illusion' I once thought was the man I loved. I don't think he was ever there to begin with.
Yes it hurts. but this is an important truth. hold on to it. he is an illusion.
My ex says he doesn't hate me, but he sounds like he doesn't like me at all.
he is playing on you wanting him to like you. we all want to be liked and when we know we have done more to deserve someone to like us than we should, it hurts. he knows this. he is hitting you where it hurts. and he hates that you have seen through him. partly because he is not getting his needs met and partly because he can no longer pretend to himself that he is decent in any way when he is left with just himself.
I just don't know what I did wrong.
The reason you cannot think what you did wrong, is because you can't find something that is not there. he did wrong not you.
And I am sitting here crying again.
it will get better. this too will pass. I actually laugh now at some of the ridiculous shit my FW used to come out with because I see it now, he is fucking ridiculous.
He really believes I am the abuser.
he would like you to believe it. he almost certainly believes he is a victim. he entire way of life is totally invested in oh boo hoo is it not such a shame for me. I doubt he believes you are an abuser. and even if he does, it is just yet another things in the litany of ridiculous things he believes, like he is too good for work- did he not say he thinks he is a genius?
and then look at you. just look at you 
driving in just one week
at university 
loving your course 
in your new house 
NC for 7 days 
not because of him rose, despite him. because of you, because you can do these things because you are worth so much more. you really are amazing, never forget it. 
it is lovely to see you again. glad you have been busy doing so much positive stuff.
nothing can drag you down if you are not holding on (to steal a phrase from raisin)
