“But my question here is – WHO IS THE VICTIM?”
No victims. But assuming he is Ashkenazic and gave his wife a standard Ashkenazic Orthodox ketubah, he has a halachic obligation to support her, even if he has to quit yeshiva. Even if he has the potential to become the gedol hador. (I think Sefardim may actually be able to put stipulations in the ketubah; any Sefardim able to confirm?)
