how to come to terms with a relationship ending you know isn’t right for you?

I have been knowing my relationship is not for me for quite some time. there has been so much narcissistic abuse and he’s the one who ended things with me. there have been so many signs from God since my breakup that solidify this man is not the one for me but i am still having a hard time accepting it, ive posted on here before about a few things he has said to me and all comments were telling me to leave him, i know that God saw i was not removing myself so he did it for me. i know that healing takes time, but i do not want to spend another second being upset over him. he does not deserve my love or tears and i just want to forget it. please, if anyone has any advice on how to move on i would love to hear it.
