Having had my time wasted by a shadchanis who was obsessed with height and must have calculated mine from the top of my best Shabbos hat to the bottom of the heels of a pair of thick soled shoes I wear in the house (how she ever knew I had them is beyond me), I know what kind of characters are involved in sheker diber kesef notel.

I don’t think learning full time is for everyone and in my community it is unheard of. But if someone really wants to dedicate her life to supporting a sincere learner who isn’t looking for a meal ticket, let her have her chance. He’s waiting for her since before they were both born!
I just hope she doesn’t plan to support her husband by working as an author, an editor or a journalist :)!
