Lying is acceptable to most people. Not to me. I’ve had way too many people lie to me about serious issues that have harmed me.
If I need to be able to trust someone, and I know they are lying to me – especially to cover their own issues/wrongs that have hurt me – that is the end of any trust I can ever have in that person.
You cannot trust a liar, especially those who can’t even admit they are liars.
Lying to someone is abusive, a betrayal and it is deliberate behaviour. It shows an absolute lack of respect, lack of honesty, lack of empathy and shows how self motivated and weak the person is. And how they are willing to hurt, harm and betray someone, for their own needs which are paramount.
And once someone lies, you are very unwise to not consider what else they have been lying about – as it is unlikely the first lie they have told you.
