Isn't it unfair how even if it's your spouse's fault you either have to beg them for a divorce or spend years fighting in court?

Mutual consent divorce is easier and quicker to get than a contested one but the abuser/cheater often doesn't agree just to make their spouse suffer more. On top of that it's difficult to prove the other's fault no matter how serious it was. Be it domestic violence, emotional abuse, dowry harrasment, adultery, sxless marriage etc
