I find desperation as pathetic in either a man or a woman. What I notice is that it desperate behaviour can show itself differently depending upon the personality of the affected individual. For instance: I've seen both desperate males & females cry, beg & plead. I've seen another sort of desperate male & female go after their suspected rival if their relationship is ending because their boyfriend or girlfriend ran off with someone else. This kind of desperation is behind a lot of high school type bullying & cyber-bullying. There's another kind that is scarier still: it is the one where the scorned partner says (or thinks) 'If I can't have her/him NOBODY can.' this one is behind so much domestic violence & spousal murder that it isn't funny. Where the 1st form of desperate behaviour looks like weakness, the 2nd looks like bullying & the 3rd looks like narcissistic control, all 3 are expressions of desperation.
I remember someone from back in school. Her boyfriend was cheating & she expected to be dumped any day for girl B (typical high school soap opera fare). Her reaction: cry, plead & beg. The guy wasn't swayed by this but became defensive & lied about cheating with girl B (girl A gossiped this info all over the school). Girl A upped the ante by becoming seriously histrionic: she began starving herself, she began cutting herself, she began following the guy & spying on him like Sherlock Holmes. <----BAD ideas. During one of her spying forays, she caught him with girl B. UH-OH! High seas drama ensued: instead of attacking either party as many scorned lovers would, she whipped out a bottle of pills & in a theatrical rant, gaaked the whole thing down (!) She wound up being carted off in an ambulance as we stunned teenagers all stared (for once the Aspie was NOT the only one staring!).
Somewhere in there are a bunch of lessons for both guys & girls. Either way, I think we recognize desperation & call it that more readily when it is the crying belly-aching kind. When we develop the skills to spot it as the motive behind other more aggressive-looking reactions, we see that it is much more alarmingly pervasive than we'd originally thought.
