when their actions don't reflects their words you have no idea how you should think about them

Sounds like they also don't know what to think. Sounds like they believe in their lies.
I did things unlike I wanted. I said words I didn't mean. Usually when I subdued to hope or panic.
Humans evolved a society filled with destructive rules and false conclusions, hard to fight when they surround us.
If that's the reason, humans are to blame... but not people, including you.
If you don't know what to think, it helps to expect anything.

They still don't believe me.

That's their problem not yours.
