My wife got into a dispute with a client over unpaid services, the guy was a day late in payment. I called him to sort it out, he said he would pay the next day. I relayed this to my wife, and left the house to go to a dinner with some of my close friends.

As I'm out, she texts him that he's messing with the wrong woman. They get to a heated exchange via text. He calls her a prostitute, she calls him a muslim terrorist - nasty exchanges all around. My phone is blowing up about how pissed she, and the guy (who's likely drunk) is texting me how he doesn't want to pay because she's being rude, also calling her and me names as well. I'm out and trying to balance this situation while having a good time with my friends - I take the high road and ask him to be civil, that nobody works for free, and that he should do right by us. He responds he won't pay out of principle and that he would fuck me up in a fight. I ignore him.

The next morning, he pays me half of what is owned. My wife threatens to press charges and he pays the remaining amount. Afterwards, she attacks me saying I didn't do enough - that I'm a pussy because I didn't send him death threats and didn't go to his place to beat the fuck out of him, that I'm not risking jail time to defend her honor. I'm a big guy, I don't believe in resorting to violence and death threats unless I or someone I love is in real danger. I'm not starting wars over petty insults. The dude is a piece of shit but he's not worth it.

Anyways, I've been getting the cold shoulder since, she's telling me her old fuckbuddies and friends are willing to come to this man's address and tear him apart - and that I'm not a man and she's going to leave me soon and that she'll never let this go.

It might be worth mentioning that she suffers from PMDD (think PMS on steroids x 10000), so for about 2 weeks of every month she'll get set off by anything and have a massive fucking outburst or fight (she once physically pushed and wanted to fist-fight a bouncer because he didn't like Mariah Carey).  Once it's over she ends up being her sweet self. 

Am I the asshole?
