A Mamin was saying marrying someone who is OPENLY a little less frum than you – that’s bad.
On the other hand, marrying someone who is slightly more frum than you, (but around whom you can comfortably act frummer and behave just as frum as they are) – that’s good.
Does that make sense? Won’t that mean that your spouse is marrying someone less frum than them–and then they will have a bad marriage (and therefore you as well)?
