I have been NC with my ex for a month tomorrow.
It was a particularly volatile and abusive relationship (and breakup). I wont go into massive details about the things he did, but during the breakup it involved sexual assault. We werent together that long (just over a year), but i suppose because of all the abuse it felt intense.
Anyway, after a rather drawnout breakup with umming and ahhing from him about whether we should get back together, i finally blocked him from my life. In the weeks that i did this my life took a much better direction - i got a job, i am about to sign for a flat with my best friend in a new city, i feel good for the first time in ages.
But hes still in my head. Im so ANGRY with him and myself, the thought of me being intimate with him or sleeping next to him makes my skin crawl. The thought of him being happy makes me angry. I want him to suffer. Which is terrible and it makes me feel guilty. I spoke to my therapist about it and he just said "i understand your anger, he sounds awful". But i dont think its healthy i want to feel nothing towards him, i want to sleep without him being in my night terrors 
Can anyone help me please
