It depends on who this person is. If it’s a relative, you must keep
the kinship with them, even if it’s the minimum. You should also make
sure that this is not Satan playing with Your mind and making you
think in this way.

If I fear or know for a fact that a person always talks behind my back and tries to hurt me and shares info with others. Can I avoid her, turn down invitation or just continue to meet and mix? I feel it’s hypocrisy.
