That's good news, OP. I'm so glad you've decided to end things with this abusive man.
I echo PP who recommend that you take a firm stand, and make a clean break.
Block him. Delete his number. Delete his pictures on social media (if he has any).
Just ghost him completely, and do not give him a chance to beg you, or persuade you, or demand an explanation from you.
You will be safer this way. These men are very, very good at drawing women back in. They do not like women having the upper hand at all and they always feel that they should be the ones who finish a relationship.
I hope you find peace with your decision and that he doesn't start trying to harass you at all. Please keep posting if you find it helps.
If you waver, remember the women he has abused in the past. Remember our stories on this thread. Remember that we're all behind you and willing you to succeed in leaving him.
If you do decide to try to give him an explanation I believe that would be a grave mistake. You will easily get sucked back in - because these men are past masters at manipulation.
I expect you may get a few "but what have I done!" messages from him if you leave the door even slightly open.
It is safer to make a clean break.
