i grew up with my mum watching the main british tv soaps like eastenders, and i remember loads of storylines concerning violence by men towards women, yet none the other way round, or between same sex couples for that matter, yet i've come across cases of wives mistreating their husbands in one way or another in my local area and at uni as much as i have of husbands mistreating wives, tho i thankfully don't recall violence amongst people i know, mainly cheating and locking the other out overnight
my main point is that in all the tv shows i was subjected to, which are supposed to be realistic, there was a 100% rate of women being abused (often very violently), and most of the time in the same shows, when the women cheated on the men, they were portrayed as the good guys, or at least in no way as harshly as the guys who cheated on the girls. often, the innocent husband was seen as a bad guy for somehow failing the wife by being the perfect husband (which seems a bit wrong)
as for my personal experience, my ex accused me of cheating on her with a girl who i had never spoken to, and also with another girl because i walked home with her one night when she lived basically next door (knowing full well that the other girl was in a committed relationship). the thing was, my ex was constantly flirting with this other guy (and one of our mutual friends at the time joked that her relatinship with her bestfriend was a bit suspect, which i ignored) and apparently i was an asshole for getting jealous for good reason, but was as much an asshole for apparently flirting with this girl who i played darts against once or twice... and i wouldnt describe it as flirting...
sorry, went a tad overboard there... but you get my drift
