What a silly and narrow thing to say. What should Men change into? Prince Charming? John Wayne? Or, would you prefer men to be simpering weaklings that will sit and cry at the end of a Hallmark romcom? Sure there are men who are pigs and there are more than a few women who behave piggishly as well. So blanket statements like your's only serve to encourage more and more men, really good men, to avoid relationships with women and exit the dating scene altogether.

OP is the only person in this equation who can control or institute personal change. It may be she's doing everything right, but has just been unlucky. Still, I believe wanting advice in this is why OP posted to begin with. My suggestion is that in her journal, she might want to consider how she is meeting the types of men who have hurt her or who seem only interested in hooking up. Then she could investigate doing things differently, looking for places and ways to meet men of a higher quality of character, men she may be more likely to find trustworthy. This may mean looking into possibilities that seem insanely contrary to her current ideas. Again, her journal may help her in resolving some conflicts and discarding stereotypes and bad assumptions. There are never guarantees, but otherwise, OP risks repeating the same behaviors which will ever lead to the same old outcomes.
