One cannot, I think, base successful marriages on the notion that the principals can and should be carefully typecast, regimented, pigeonholed, manipulated, and choreographed to the huppa. Case study: a whole society appears to be trying it that way and is writhing in anguish.
In my opinion, typecasting and all the rest can work only as far as the huppa, and even then only if the principals are taught that they’re types and not people. Their resumes and investigation files don’t explain how they’ll cope with the deviations from type that each will display as time passes. And they will deviate, unless they’re still play-acting as though married life were a shidduch date. The “shpitz” who burns out at age 25. The eidel maidel who wants to join a gemara shiur. The haredi-lite bachur who turns to the Right. Everyone in this forum can add examples.
