The Hijab Problem?
I think the problem under question is not the Hijab problem , it is just one visible leakage the walls of Husband wife relation ships.
These guys were husband-wife for 11 years and now a problem arises that the husband enforces her wife to do hijab, and she is feeling incomfortable with it , there would be other major issues among this couple , they should understand that, the only way is communication , I think a very big communication gap have been risen among them, they should first start communication.
Ya.....! , since the only girle or wife is more concerned about the matter , so i think she should obey him now , as feeling not well is a little thing but wounds on body of this relationship is something very dangereous, so be patiant and obey for some time , if you feel confortable using Hijab later too, later on you can bring on track your spouse too.
