The backstory: I've been doing business with a shop that does performance work on cars for about 10 years. We will call the owner "Bobby". On top of working on my cars, Bobby also pays me a small commission for people I refer to his shop that get work done so we've had a lot of communication throughout the years.
Our relationship is strictly professional. No hanky-panky or anything remotely inappropriate. Our conversations are always based around cars & lighthearted banter & shit talking.
Since they were just toddlers, Bobbys kids have always been at the shop with him.
Friday night I see his car at a casual restaurant by my house, which is about 60 miles from his side of town. I text him & jokingly ask him "what the hell are you doing on my side of town?" ... he replies & tells me to come in.
So, I go inside with my son, he has his 2 kids with him & is sitting with a lady. Right away he says "This is my wife, _____" & I reply "I had no idea you were married", well, instantly she freaks out. Starts screaming about we're having an affair & all kinds of crazy stuff.
I tried to explain that he & I have a PROFESSIONAL relationship. We NEVER talk about personal matters. I simply assumed he was single because: 1. his children are always at the shop with him & 2. I have never met her or seen her in the shop before & this is a family-owned business.
My question is: Am I in the wrong? How can she not see I meant no harm & that this was a simple mistake in my choice of words?
I look forward to everyone's feedback
