My [34/m] wife [31/f] has caused me to lose all of my friends because of an incident that happened on Monday. I may have lost my job?

Of course I'm going to use fake names for this. I don't need my friends getting more ****** off at me in the event that they browse this Forum Section. I need to give background because this incident didn't really come out of nowhere and so it may be a little long.
Four years ago Britney and Roger became my new neighbors and my wife and I have been close friends with them since Britney knocked on our door introducing herself with a pie(she's that kind of person). Roger became my best friend and when I lost my job, he gave me a position at his company. It paid more than my old job and when my dad was dealing with health issues, Roger gave me an excessive amount of paid time off. I simply cannot stress how much Roger and Britney have done for us.
Last May, Susan and I started trying for children but it has been very difficult. When Britney became pregnant, she started saying nasty things to me about her. It really reminded me of high school antics because she would spend a day with Britney but as soon as she got home, she's criticize her clothing, etc. She would complain that Britney got more attention that her when they were in public. When Britney was honored at her job, Susan said she would show up to support her but made me stay home that day with her.
I honestly began to look at my wife differently but I told her that although our situation is painful, we should be happy for our friends. I asked her if she could try her hardest because Roger and Britney would be happy for us.
On Monday, we were having a bbq at Roger's and my wife noticed that Britney was wearing a new ring. She asked Britney wear she got it from and she said JC Penney.
My wife said there was no way that she got the ring from there and to be honest. It seemed playful when Britney told her, "from my husband" but Susan actually started to get angry. I also thought Britney was lying about getting it from JC Penney but it wasn't a big deal and if anything, it was rude of my wife to ask.
Apparently, Susan had been harassing Britney via text and I only found out when Roger messaged me saying, "You know what, I got it from [company name]". I told Susan and she looked on the website so that I can order the ring for her. I said maybe just to calm her down. We found a similar ring on the site that is literally a quarter of a million dollars. Susan lost it and threw her phone at the wall, causing it to break. We got into a fight because of that and I left to stay in a hotel. Honestly her behavior had been getting out of hand (more happened but this is getting way too long already).
I blocked her number because she wouldn't stop texting/calling me. I planned on speaking to her in the morning when we both calmed down but I woke up to an email that stated Britney and Roger must be involved in drugs to afford. Nevermind Roger owning a successful company and being essentially a trust fund baby.
It was a very formal email with screenshots of the website and similar ring for "proof". She mentioned how Britney and Roger were flaunting their wealth. Nevermind that if Roger hadn't told me about his inheritance while drunk a few years ago, and knowing he owned the company I work at, I wouldn't know they were wealthy at all. We are literally neighbors in the same upper-middle class neighborhood and they only own Hondas.
Worst is that she accused Britney of not being able to be a fit parent because of her childhood abuse. I didn't know that Britney was abused and she shouldn't have mentioned that. The entire email was disgusting and oh yeah, she copied ALL of our mutual friends with Britney and Roger and she even copied them!
Since then, I haven't been able to get in contact with any of my friends. I've apologized to all of them for my wife's behavior and I tried to talk to Roger in person but he said he was busy.
Today at work, I was scheduled for a meeting with a supervisor. I tried to ask what it was about, but she didn't respond to my email. I could be overreacting but I feel like it has something to do with what happened this week.
I tried to get Susan to apologize but of course, she's the victim in this situation. She said she would attend marriage counseling with me but I'm at my wit's end.
My personal and professional life is in shreds right now and I don't know what to do.

--- tl;dr: Wife sent nasty email to friends about my best friend's wife. My best friend also owns the company I work for. Is there any way to fix this?
