oomis,
I would agree 100% were it not for the fact that unfortunately in too many cases,though not all, the type of man who would refuse (as per halachic mandate) to give his wife a GET, is probably not the safest bet for strengthening that marriage.
You make an excellent point. Clearly a fundamental part of creating good marriages is educating young women and men about taking time to watch out for potential warning signs of abusive tendencies. Gila Manolson has an excellent section about this in one of her books about dating.
