Susan, in this situation, the liar is protecting himself. Even withholding information is wrong here. I've been there. My neighbor knew that my ex was meeting another woman and where but she didn't tell me until I kicked his butt to the curb. She could have saved me many years of wondering.

She said she was protecting ME but I wonder if she wasn't really protecting HERSELF, not telling so she wouldn't get caught in the middle of it. I would have much rather known at the time it was happening! ggrrr It still makes me mad!
