I feel you and for you. I do.

I actually found the comment he left you to be quite honest. Even in the situation you describe, and I understand your hurt and that you don't think you would ever act that way, and maybe you wouldn't, but under some circumstances where you felt that self-preservation required it, you might, and self-preservation does not mean that the person you might ghost has acted harmfully. All I am saying is that the only person one must unconditionally love is ourself, and sometimes that requires hurting another person. I see his comment as a pretty good attempt at an apology. It's certainly an admission.

Maybe the explanation would have hurt too? Maybe you would have tried to talk him out of the decision, a decision that he felt was best for him.
