No. I agree with AustinMan.
I've been in the same situation myself.
I went a step further actually. I dumped him by (terse) text, blocked him and left his stuff with the concierge and changed the locks.
I've never looked back and felt that my actions were relevant/appropriate.

No, because the answer you're going to get might be mean, and you don't need to dig your own grave with your own hands. You don't need his approval to start living your life... just start now.
Why even bother, force yourself to move on. Ghost him, he deserves it for how little respect he showed you.
