It actually simpler and more complicated than that.
Simpler in that women just process information differently. Not faster or slower, just differently. They think outside the box, all the time. They internalize everything, and rather than thinking right or wrong, its more emotionally satisfying. Its why women are superior to men at alot of jobs, they care. They make it part of themselves, men only care because of the monetary reward they get for doing it right.
Its more complicated because its unpredicatable. Don't be bitter, just appreciate the different outlook.
Judging from your post, you had a fight with your girlfriend and its taking her time to get over it. She's just processing it. She may get over it without a solution, buyt find another emotinal release.
That's just women.
