HaLeiVi -“We hope he will get married, but not by hiding it.”
You’re lucky you don’t know the person’s name because if you did you were just Oiver LH and perhaps Motzay Shem Ra!
You just assumed the man was hiding some info -who says? The OP never claimed the the Kallah didn’t know, just asked if he should get involved. Unless he spoke to the Kallah -he has no way of knowing what she knows. And he said -he didn’t speak to her.
“If you know someone with such a problem please do not keep it a secret (from the appropriate parties). You rightfully feel sorry for him, but tying up an unsuspecting person and shattering her dreams and life, is not a better option. Let’s Daven that he should find his Bashert and have a full Yeshua.
I won’t judge his parents. They are desperate, and are blinded by their worry for their child. However, I don’t know how such people face their children-in-law, their victims.”
Again this is your projection. This is only correct if you know that they don’t know, eg. you’re the Shadchan. This Krum way of thinking probably has caused many people to Not get married. Did it ever occur to you perhaps people are willing to overlook certain things? Sometimes they are willing to overlook these things if they aren’t public knowledge. So let’s say the Kallah doesn’t mind marrying a guy with Bipolar, but she thinks that it’s hush-hush, but then every Tom, Dick and Harry are calling her and her family up saying -“Did you know that the Chosson has Bipolar” (Or any Chessron)?
I can see many a Kallah getting embarrassed and calling it off.
These people who did this just committed Rezicha -all in name of Shomayim!
