Its interesting to watch the evolution of opinions. From questioning, to being just so certain. Many gedolim have allowed and encouraged insignificant details to be misrepresented. But they were in the business of doing what Hashem wants.
Looks like some people would REALLY benefit from a rov or rebetzin, to whom they will really open up to and disclose everything they are feeling, including the terrible LYING they feel has been done to them, in order that they can be guided by experienced ovday Hashem who will help them work through their problems in getting through the dating process (which they cant seem to get by) in order to get married.
A rav/rebbie/rebetzen/mechaneches can help, only if we are forthcoming and not worried about exposing the liar and are actually willing to LISTEN!
