The reason why dudes hurt and make females cry because they get a sense of power and control about it which is why they continue doing it. Also it shows how much the females loves them so it's like they have her wrapped around their finger.
Seems like some women like being hurt because it shows that they're going through something and one day they might or want to have somebody so they can say that stupid quote "I went through a lot of bad ones to get a good one". They want to have stories to tell, to make it seem like they been through war. Or maybe they're weak and stupid which is why they let dudes get over.
