Is my Sister a Pathological Liar?

Fri, Apr 5th 2013

One year ago my sister divorced her husband and ever since then she has been extremely unpredictable and lies constantly. She lies about things that really it doesn't even make sense to lie about. For example, whether or not she's at home, or what she's doing that day.

She has a teenage daughter and has even driven her to the point of running away. She tells her daughter that her father does not care about her even though her father tries so hard to be in her life. She does not allow anyone in her daughter's life anymore. I have no idea why this is. She even goes to the point of spreading rumors about our own father and mother about how our father sexually abused her as a child. However, she is in her 30's now and does not even make sense to bring up at this point.

We know for a fact she is lying about that because we all know the real story. She also seems to have an obsession with trying to make everyone hate their fathers. She hates her own parents, though just last year she loved them, and now she is trying to make me hate my father (we have different fathers). She is also trying to make her daughter hate her father as well by telling her all these terrible things about him that aren't true.

She has been constantly lying to everyone about anything she can ever since about a year ago when her and her husband divorced. It has come to the point where my family and I can't help but think she must have some sort of mental disorder. Pathological lying disorder? I am not sure, please help.
