You are still being very vague. Yes, if one does love Hashem it is not possible to do anything other than that which he has dictated thru the Torah. Rabbi Cordoza speaks of this in a shiur called, “Halacha as a symphony”. He said that if you TRULY understood the meaning and purpose of Yom kippur, you wouldn’t even think of eating, you would chose for yourself the very dictates that Halacha has set out for us. Truly loving Hashem brings a person to only want for himself that which Hashem wants for him.
But that is very different than saying that you love Gd, so you know that He doesn’t care what mitzvos you chose to keep or how you keep them. That He doesn’t care if you wait between milk and meat, if you check your lettuce well, if your skirt covers what it should.
I have heard your words used in both contexts and they are not the same. I don’t know if you are deliberately being vague about your meaning or not but the latter scenario is just an illusion.
