Why do all women i ‘ve dated keep grudges for long?

I know everyone has probably heard at least one or two stand up comics tell jokes about how women can remember something from years past and throw it back in your face when you are having an argument with her.Well everyone makes mistakes. And depending on what exactly you’ve done, and the manner of your apology, things really need to be buried and left behind. But this doesn’t apply for a lot of women out there. Very often, you talk over things with her and, just when you think that the hatchet has been buried, she brings it up when you least expect it, leaving you to wonder whether you will ever get past it. Will you always have to be reminded of every mistake you’ve ever made?Every argument will end with that one thing that you’ve done previously. And whenever you try to castigate her for something she’s done, she will remind you of the time you did even worse. If something is so bad or so unforgettable that the trust is totally gone, then its better just let the relationship go rather than tormenting the man over and over again. They can’t change what already happened.
