Aygart -
The husband in Rebbe Moshes tesuva where Rebbe Moshe annulled the marriage (which this case is supposedly based off of) was in a mental institution, walked around without clothes on and had tried to kill himself. Even if he gave a get it probably wouldn't have been good because of his mental illness.
The current husband, Aharon Friedman for the past bunch of years (not sure exactly but I think more than 5) has worked as the tax counsel for the House Ways and Means committee. In other words his boss until last month was Congressman Paul Ryan who is now the speaker of the house. His job entails dealing with other high ranking members of Congress, lobbyists and CEO's of fortune 100 companies. Do you think that someone who has had this job for year's is mentally ill like the husband in Rav Moshes tesuva?
If you read the letter from the Baltimore Bais Din it clearly states that when asked why she wants a divorce Tamar said that her husband wasn't social enough for her. Don't you think that if her husband was suffering from an incurable mental illness she might have mentioned that to the Bais Din as to way she wanted a Get?
The expert psychologist who said that the husband is mentally ill never met or examined the husband and only based the report off of what Tamar said about him.
Aygart - i have made 3 points to explain why i think that the husband is not mentally ill - your thoughts.
A. You're assuming this case has to be an exact corollary from R' Moshe's case. That's your first mistake. R' Moshe's heter moved the goal posts, there's no reason contemporary halachic authority can't do the same. Granted, the new standard from whoever granted this heter hasn't reached acceptance in the velt so it probably won't be binding.
B. Being able to hold down a job - even the type of demanding job he has/had - is not indicative that there's no mental disorder that would make a marriage unbearable. It's certainly not a proof as you try to spin it.
C. Maybe she was told not to tell the BBD about the mental illness for fear that they would say he's not able to grant a valid get? See, I could speculate with the best of em in this thread.
Assume you are correct that he has a personality disorder - is that the threshold that Rav Moshe set? Have you lost your mind?
Again, the goal posts move every generation.
