Gaslighting/Ghosting

The film Gaslight en.m.wikipedia.org/wiki/Gaslight_(1944_film)

Yes. Gaslighting is different.
It takes its name from the old film Gaslight.
It means to make someone question their own thinking; even their own sanity.
It’s often done by narcissists and psychopaths.

I’ve been the victim of it.
A man I worked with was having an affair with a student in plain sight, but tried to made me feel that it was all in my mind.
I was his wife’s friend.
His wife was on maternity leave at the time.
It was horrendous

I agree Argymargy. All sorts of people behave like that don't chase them and lose your self respect. Let them go unless they are close family of course. Painful but better than hoping and hoping for years.

I think gaslighting is very different from ghosting. Gaslighting is when you convince people that they have misunderstood, misread or misremembered things. The reason is always nefarious - the motive may be financial, sexual but usually overall control of the person being gaslit. You could look it up.
