When does the equilibrium of keeping frame and pissing your girl off get broken?

Example: Today I had a stupid situation with my woman. She was wearing no bra, black top, nipples pressed against the fabric. I told her I couldn't concentrate with her nipple like that, in a playful way.

She has small boobs and is very conscious about it.

She asked if I say that to other women too, instead of being playful or saying "shut up" with a smile or anything nice, so I went full honest and responded "yeah, if it's a friend and I'm just joking around, sure I'll say it too."

Boom! anger, immediate anger and calling me out saying I was out of place and that cheating would be the only step up to that. Silence treatment, no physical contact, the usual.

I didn't try to get her out of it, she said she knows I don't care when she's angry, I shrugged and smiled and said I didn't care when it wasn't about important stuff.

Anyways, my question is, do you ever think you're just pissing her off unnecessarily sometimes? That's how I felt today, but I didn't change my stance on the subject because that would achieve nothing.

When do you decide "you know what, I'll let this shit test or shit question pass" just for the sake of peace or not driving her mad?

Thanks.
