I do understand the "believe none of what they do and half of what they say."

You have this backwards,

Believe actions not words.
And not all of their actions/

It should be:
Believe none of what they say and 50% of what they do.

Let go of the OW, she is a symptom not the disease.
DETACH, DETACH, DETACH!
