“Their is very good reason for the PRE research, and risking a shidduch going through without the research is not something most parents or children desire. And rightfully so. “
Boy oh boy! If my parents had done research of ANY kind, I would not now be married to my unbelievable husband. He is a BT, his parents were not frum, his mother had a stroke at age 42 that left her blind and crippled for the rest of her life (35 years more), plus she had rheumatoid arthritis. Had anyone talked about the externals about them, it would not have been considered a good shidduch on paper. B”H nobody did that type of checking in those days, but judged people on their merits and middos.
