"Heterosexual women who've had long-term relationships see their man fall apart. They go, "I'm giving him my whole life - I'm giving him my love, I'm cooking for him, he's got this great sex, he's got everything. Why is he so miserable all of a sudden? Why does he want to get away with his buddies and look at other girls? What is his problem?" It seems like something that happens to men, they feel like their manliness has been chipped away and destroyed by being with just one woman. They feel resentful and they're passive-aggressive."
