People have the right to make a choice if they want to marry someone who is bipolar, borderline-personality disorder, suffers from depression or other meental illness – just as they deserve to know if the shidduch suffers from chrons disease, or has another serious disease.
This isn’t a game. It’s a marriage. None of these conditions can ever be held from someone else.
