I know of sisters and brothers that were marked for marrying a worldly person, the elder that marked one of them, was having an affair with a sister in the congregation. It came out later.
Others have married a person that ticked all the theocratic boxes only to be disappointed later as they were not very nice people after all.
Still others have lost opportunities with valid worldly people they were in love with and they are alone now, getting older, and without much of a career going on for them either, as they are wasting their time away pioneering for this corporation and waiting for the new system, to be able to do all the things they didn’t do in this life. Sad.
