Absolutely.
My RAF's lies began to hide his drinking.
Then the lies started being about things that were totally unrelated. It became so ridiculous. He was lying about things that wouldn't have mattered or had any consequences.
Then again, I was no better. I began lying to hide my feelings and my snooping. I would lie about seeing or talking to other people like friend/family. In my head I was afraid he'd be paranoid that I was talking about him or our problems... giving him another excuse to drink.
I was lying thinking I could manipulate his addiction.
Pretty sad.
