How bad does it have to be before God will except your divorce ?
The Bible speaks of divorce specifically for abandonment(spouse leaves you or just disappears) or for infidelity. Personally I believe it also acceptable to divorce if true and real abuse is going on - but there are some people who abuse the "abuse" idea just to get divorced.
I think if you are getting divorced just because you can't stand the person that is not God's will, at least not from what I can see in the Bible. However even if you get divorced for an unbiblical reason(which would be sin) God does and can forgive all sin(even unbiblical divorce).
Just my two cents.
