About 15 years ago, I was privileged to sit near R. Noach Weinberg ZT”L at a dinner.
During the course of the dinner, a young lady approached him and asked him how a person recognises their basheert. (Although I did not know this young lady, the impression that I got was that she was quite desperate to get married).
R. Noach answered her and said that the Gemara tells us that Esav was the basheert of Leah (Rashi says as much in Chumash) and that Leah cried (until her eyes were tender) and merited not to marry her basheert!
He then advised her to go find a frum boy who knows what marriage is all about!
Anonymous123, don’t look for signs. Be guided by your seichel. If there is something wrong, go discuss it with someone who truly understands these issues and has your interests at heart. Be prepared to walk-away, if so advised. Remember, you are the one who will live with the consequences of the decisions you make.
Hatzlocha Rabbah!
