“This couple needs to find a rav (and, possibly, a marital therapist) to determine where to go from here. Holding her to the letter of her agreement may well spell the end of the marriage before the five years are up. “
All this shows is that yur not machshiv Torah learning. If she agreed to support his learnign for five years then she has to do what she agred to. Doesnt her word mean anything? You cant just say let her out of it becuz shes not happy. what if tomorrow she desides shes not happy with being married to only one guy? Are you going to allow that because shes not happy now?
