Why women are usually the ones to initiate a breakup or divorce in a good relationship?

I imagine most guys don't usually point out all the problems in the relationship because some don't find every small problem as a bad thing that can't be worked out because most guys see the significance in the good of the relationship.

But what seems to make women so fast about wanting to breakup instead of working things out and communicating?
