With no fault divorces, you can divorce very easily, and usually at the expense of your lover. Lets say the society is still sexist, and a woman wants to get a divorce. They get child custody, money to keep themselves afloat without work. The man/breadwinner will get nothing. If the divorce is no fault, injustices like this can happen. If the divorce is only with fault, then an innocent person cannot be harmed by a divorce or unloyal lover.
I guarantee you of those 50% divorces that some of those Marriage's could've been fixed. If more people worked at their Marriage the divorce rate would be a lot lower. Even in the case of cheating if the cheating spouse came to the other spouse and said they were sorry and was willing to restore their Marriage the other spouse should be willing to work with them and give them another chance since nobody is perfect and since Marriage is about making a lifelong commitment to each other. Because what God has joined together let No Man Separate. Also Divorce hurts Children because children Need a Mom and a Dad together in the Children life's if possible. Yes I understand divorce sometimes is necessary. But I'm trying to say that it's definitely too easy to give up on marriage in our society.
If divorce was easier, people could escape domestic violence more easily. A number of marriages were never meant to be, and if someone cheats, abuses, or is a deadbeat, people should be able to end the relationship just as easy as breaking up with someone else. Sometimes people divorce too soon, but other times it's neccessary.
If your a father, you will most likely only get visitation of your children, regardless of what you ask for. The system discriminates massively regarding this. Doesn't matter who did what before or who is best suited, you as a father will most likely lose any request for a 50/50 outcome. The system does not see you as equal. The system and gender only sees you as the expected bread winner and provider and mom as the care giver.
So seeing how the only thing that matters the most is ones children and chances are you will have limited access, then it is a lot harder to divorce as a father and easier if your the mother. Two different sides to this.
