Absolutely. People are human,and to be human is to make mistakes. You can't claim to love someone if you can't accept them for their imperfection and extend to them the same grace you allow yourself for your own mishaps and fuckups.
Back a long time ago, about a year into my relationship, my partner managed to spill an entire crockpot of apple cider all over the backseat of my car she was borrowing to take to a friend's place. I reminded her several times to make sure to shut it tight and to secure it somewhere on the floor in the middle of the rest of her stuff so it wouldn't tip and spill.
Of course she didn't do any of that and it got absolutely all over my seats and was a sticky gross mess. I later heard she spent the whole rest of the night over there fretting and worrying about how mad I was gonna be when she got home. And she was literally dumbstruck when my only response was "Alright no worries, sounds good" when she'd gotten back and offered to pay to get the interior detailed after explaining what happened.
"Aren't you mad," she asked and I just said "Not really, it's fixable and you already said you'd fix it, not much to be mad about."
