I’m so very sorry for your pain. I agree with the others that the question perhaps should be more focused on YOU instead of HIM. You ARE enough. I myself have questioned these things after a breakup and ultimately realized that it’s always about the other person, not you. When the time is right and you have allowed yourself to heal, my hope is that you will realize he has given you an opportunity for a better life for yourself. PS: also, the odds are quite high that the other relationship will eventually not work out and he will just go on ruining lives because he doesn’t seem very emotionally self aware. Take care of you 💝
