The nice-guy type, when he meets a woman who seems to share his trusting nature and appears as interested as he is in true intimacy, will naturally believe he has found his perfect match.
He will not realize that the nice-girl behavior that women with traits of BPD initially display will be followed by behavior that is anything but nice.
He must learn that although the woman with traits of BPD may closely resemble a nice-girl type, the motivations behind her behavior are quite different.
But it may take more than education about traits of BPD to convince a nice-guy that the love of his life was not who he thought she was.
And it is the nice-guy type’s mistaken assumption that deep down the woman with traits of BPD is really just like him that keeps him from recognizing her limitations as a relationship partner.
