Hi Jamie,
I think if he texts you again you should definitely just NOT respond. And no, I don’t believe that he will change. You probably won’t get closure on this from him so you have to make the choice to give it to yourself. Give yourself permission to walk away from this. You tried to make it work, what he has asked of you is not reasonable and he’s finally resorting to threats, insults and blocking you. Consider that a blessing that he’s blocked you. It’s time to walk away.
You might find this helpful…it has been for me as I’ve been going through my own break up and soul searching. https://www.elephantjournal.com/2015/06/the-toxic-attraction-between-an-empath-a-narcissist/
