That absolutely was the context you used but maybe that is not how you intended it.
If that is how it was used, you are correct that is not how I intended it.
So let's get this straight, you are following the psak of your rov to wear a mask when you go to shul but for a chasuna, then you are going to ignore that same rov? Why?
This really does sound like a case of כי בשרירות לבי אלך
The shul requires masks because "when in Rome...". Several local rabbonim who require masks in their shuls did not require masks at weddings they made in the Tristate area because they believe, as many other Morei Horaah, that they are not necessary. My Rov does not believe masks are required at weddings al pi halacha.
If we required (at a chasunah in the Tristate area) masks, social distancing, quarantine or testing it would be extremely odd, as the 20 weddings in the TriState area that these same people have been to in the last month did not require them. You may call it שרירות לבי but it is also the the norm. To quote from this week's daf yomi, puk chazi mai ama d'bar- go out and see how the people on the outside act.
