It's a 'hanging offense' in the USA. Hell, if a wife wants a weekend out on the town at her hubby's expense just dial 911, scream and hang up then slap herself while her hubby sleeps on the couch or in the 'big chair'. He'll wake up in handcuffs and she'll have the house, cars and his money all to herself for the weekend.
Party on!
If she wants to extend the party she can execute a restraining order (at no cost to her) and have a ball in his house, driving his cars, spending his money until the trial (30-60 days later) and he can't do a thing about it. As a matter of fact if he even calls, texts or comes within 1,000' of her it's back to jail for him while she and whomever are whooping it up at his expense. Drinks 'on her' (think Cuervo 'belly-shots'). Then by the time the trial date comes up he'll crawl and beg her to drop the charges because he's presumed guilty until proven innocent.
In the USA it's almost against the law to be a Man....unless you're gay, not that there's anything wrong with that. Macho isn't currently trending here.
The story doesn't give enough detail. It sounds like they were in bed, (? who slaps their wife in bed unless she asks him to?), he was dogging it and got a little too happy when he popped her on the yams, making her hit her head on the headboard. He wasn't in trouble until he busted out laughing at her. He should've finished what he'd started, then they could have laughed about it together.
BTW...IMO, Manny only retired to avoid the 100 game mandatory substance abuse suspension. That would've stopped him from getting paid.
