How did you get over your narcissistic ex ?

Currently mine cut me off cold and told me he doesn’t love me and never did. And that I’m a loser bitch, life ruiner. That his life was so much easier before me. The List goes on and he lacks accountability. His words definitely hurt. He was physically abusive to. So currently he has me blocked and won’t talk to me. I did nothing wrong. We do have two babies together . So how do I get over it? While I knew the relationship was over …I guess what hurts is what he said last to me and how he cut me off completely last and the fact it’s Just been abusive all the way around. Advice .

Thank you
