Mine & my husband's best friend Dan(INFP, well-developed T) has been dating an ISFJ girl. We recently found out through some unfortunate events that she's a pathological liar(we're 99.99% sure, nothing else fits). I know she's an ISFJ(an unhealthy one at that), I could bet my life she's a 6w7. He's having trouble leaving her & is clinging on to the .01% of hope that she's not insane & a pathological liar. She's been bringing us all down with so much of her drama, her manipulations, & guilt trips- trying to tear our friendships apart & keep Dan all to herself. I have never dealt with a pathological liar, let alone an ISFJ one. Has anyone else dealt with a pathological liar? Have you ever heard of an ISFJ pathological liar? Any helpful hints/tips? She is so unhealthy in so many ways. She's way too stubborn, constantly changing her mind with serious issues, panicky, always has anxiety attacks, paranoid, controlling, WAY too clingy smothering Dan, always thinks the worst, & always tells these dramatic elaborate stories that don't fit whatsoever & ruining people's lives with it all. I'm sure she has more issues than being a pathological liar. She is 1 of the most negative people I have ever met. I guess I created this thread to see if there was a chance anyone has dealt with anything like this & to vent. THANX.
