Here's how EVERY UBM suffers. At every meeting that the "believing" partner attends, congregation members come to offer condolences. "How are you doing brother/sister?" "We missed your partner at the meeting." "Do you think he/she will attend soon?" "Things are indeed hard, very hard in these last days. *sigh*"
Also, I wouldn't put it past the single sisters to make a move. You know, kinda hint that he wouldn't have to be alone if he discarded the source of his "spiritual endangerment".
