Him using the excuse of alcohol is such a cop out. It annoys me when people act like alcohol is this invisible hand forcing you to do things you wouldn't normally. It just releases instincts you already had by removing inhibitions.
I've drunk heavily, done my share of toxic substances as have friends of mine - and we've never ended up cheating or publicly shagging where people can see. Even if you get horny and not in your right mind, you know who your partner is and where you're having sex.
Having said that, I know a girl who gets bladdered and has given randoms oral sex in alleyways (much to my horror, because she's done it close to our work!). She always feels guilty and dirty the next day, and upset when she doesn't hear from them - so it's not something she enjoys. But can't seem to stop herself. I've never understood it as she could just take them home and have sex there but it's like she needs to degrade herself in that moment.
So I don't know what or why the woman did what she did, but it was always going to be more catastrophic for her. She's the one who's lost her job, and no doubt will attract far more pervert attention than he will. And I'm sure this will go up on the porn sites too forevermore. His life may be unbearable now and he's destroyed his family, but people will get over it and move on- his career won't end. And as a rugby player he's used to awful chants and slagging off. Also he'll definitely still manage to find someone else (these scummy but rich men always do somehow).
So I really feel for his wife and kids, and the woman and her family. They'll all be impacted by it much more than he will. I read his messages to his wife in the papers apologising, and honestly it seems like he's cheated before and she's aware of it but never to this scale or where she can see it herself. Such a sleazy man.
