They claim they are your only reliable friends
Pitting his victim against everyone else is another thing a gaslighter does when he wants to control your behavior and make you believe that everyone is your enemy and that the only person you can fully rely on is the gaslighter himself. This is just a form of lying and you must not believe the person’s behavior. The world is a friendly place and you cannot be hated by others out of the blue. The gaslighter will give your examples and ‘proofs’, but all those facts are fake so ignore them. Be friendly with all people and avoid possible conflicts.
