A toxic relationship has many warning signs and it’s easy to turn a blind eye to them. The worst things you can allow yourself to happen is to be gaslighted.
I consider the experience of being gaslighted as the most difficult in life. Being physically attacked, verbally criticized, fired from your job or rejected are not as damaging as mental manipulation. To be gaslighted is unhealthy because it destroys your perception of what a ‘normal reality’ is. The person manipulating you will twist your idea of what your world and your values are. He/she can even go as far as to agree with physical, emotional or sexual abuse done to you or to others.
