I agree, but we both know that women are just as guilty as men, if not more so, when it comes to overlooking unstable behavior in a significant other. The motivation for ignoring it may be different, but the results are often the same. I've known a lot of women that have held on to psycho men in the hope that their love will change them and they always end up paying for it in the end.
It comes from a completely different motivation, like you said, but yeah, the results are the same. Ruined marriages, ruined lives, ruined kids' personalities... But I digress. Again. ;-)
