Because women can make blind generalizations about men but we can’t do the same.
If a woman were to say all men are the same, she would have an incredible amount of support. Everyone would agree with her that all men are bad and there are no good men out there. No matter how her dating history is.
If a man were to make the same generalization about women he would be bashed for being sexist. Women would go crazy and start throwing shit over someone saying they are all the same.
Truth is… if you go into a relationship with the notion that it will end up like the last, then you will always be unhappy. How can you blame the future for what happened in the past?
Also, stop getting with someone and trying to recreate a relationship you have seen before. That will never happen and will most likely fail. Why would you want a movie like relationship? Why would you want someone else’s relationship? What you don’t see is what happens when the cameras stop rolling and behind closed doors. You don’t see the actors going home because that is just a movie. You don’t see that “happy” couple arguing and fighting.
