The dictionary says
ghost somebody: to suddenly stop all communication with somebody, usually online, in order to end a relationship
so, according to the dictionary, we often say "someone ghosted someone" in an online communication.
My question is that
Can we say "someone ghosted someone" in an offline communication?
For example, a couple lived in the same house but the wife avoided to talk with her husband.
Is it correct to say "his wife ghosted him although they lived in the same house"?
If we can not say that, do we have a common phrase to say that in an offline communication?
