I wish you luck. You are definitly in a predicament. If you choose to go through what ever it takes to stay with her this is definitly a fly in the soup.
I don't think talking to the will be studiers would do any good. When it comes to your words vs what they think Jah wants them to do, you will loose every time, if they are hook line and sinkers. Besides in the end it has to be your wife's choice. If she stays on that see saw ~ your life is a see saw too by the very essence of your connection. So just be prepared to accept that if you choose to stay in it no matter what. Some here have found a measure of happiness in simular situations from what I read.
Personally though I don't have that much patience for a grown person who by their behavior makes my life ongoingly sad. But that's just me...and I honor each situation and person is different. Good Luck.
