I read somewhere that when using fogging never use it to self deprecate.

So in an instance where your wife is calling you a piece of shit because she thought you were flirting with someone and asks why you were doing it.

Saying. " you're probably right I am a piece of shit " isn't the proper answer here.

What would be a better route. I'm still learning.

Her: you're a piece of shit for flirting with X you know that?? Why would you do that?

Me: I didn't think you were looking

Her: are you fucking kidding me you're fucked up.

Me: you're cute when you're mad

Her: fuck you

Me: let's go

That seems kinda lame.

Or

Her: you're a piece of shit for flirting with X you know that. Why would you do that??

Me: I would never do such a thing I'm with you and only you pretty princess

Her: you're a liar I saw you do it.

Me: you probably did

Are any of these good ways to deal with this? Like I said I'm learning all the ways to deal with these I want to make sure I'm on the right track as I'm reading
