Does he know where you live? Might he come after you to harm you physically? If you “ghost” him, does he know how to find you to retaliate?

That’s one reason I am against ghosting without a truthful break up conversation. Sometimes, even with a break up good-bye, the guy could possibly find you and hurt you physically and become a stalker. I just see ghosting as instigating revenge from a potentially abusive person.
