There is one person who betrayed me so badly I cannot ever see myself speaking to him again; it would be unloving, as only unkind and cutting words are on offer. The right thing to do is to stay apart. I can't envision any circumstance when I would trust a snake again... so why be in the presence of one?
This is not hard for me to understand and agree with. Had to do this with several people over the years. Keeps the atmosphere clean.
