Have ever had a situation where a person will reveal their honest thoughts to you but pretend otherwise to others?

Basically 2 faced...

Example: when my uncle was sick my aunt, not his wife said to me that she felt no sympathy as she never liked him anyways.

When he passed away, we were with his wife, my aunt called his wife crying down the phone.
Even remembering past situations where he made her feel welcome.

I no longer speak to that aunt because she can't be trusted.
