Lenny, keep bugging Rav Cohen till you get a conversation with him. It’s well worth it. And that’s often what it takes to get hold of an important Rov like Rav Cohen. And my advice to you is to take his advice to heart and follow through with it. He is a highly recommended and strongly held of Rov.
lilmod, I strongly disagree with your statement declaring it generally a good idea to divorce when one spouse wants to and the other doesn’t. The Torah also disagrees with that being a general rule, as the Torah explicitly states a wife generally cannot get a divorce if she’s the only one wanting it. And Rabbeinu Gershom made that even stronger by enacting that even a husband cannot divorce his wife if she doesn’t want to divorce, whereas by Torah law he could have previously. So he felt so strong about it he completely banned unilateral divorce even where the Torah previously permitted it.
Also, I think there’s no basis for your assumption that a divorce will lead to four happy people instead of two unhappy ones. You’re assuming without reason that a) both spouses will be able to remarry and b) their second marriages will both be happier than their first. I can tell you that countless times divorcees, for whatever reason, could not find someone to remarry to. And countless more time where when they did remarry they were not happier on the second round than on the first. Sometimes they were even more miserable. And more times than can be counted, some explicitly admitted they regretted getting divorced in the first place. Even when they can remarry typically it is to another divorcee who has their own set of issues.
