My partner thinks the same of me 😞

I’m very focused on optimizing things and sometimes I just want to ask, why she is doing things her way, because I think, that I’m maybe missing something.

She always brings up the example, that I even tell her, she washes tomatoes wrong, because she used warm water.
But they are just easier to cut, when they are cold and the skin doesn’t already separate

She takes the critique very personal and now it’s mostly me cooking…
Which is fine, but I’m feeling bad, because I didn’t want to say, that she does something wrong, I see such things as external and we can improve, not attached to the person as a being.

So, when she does something better, I don’t feel bad, I try to adapt her style.
Other way round, it’s always a personal critique it seems

But I’m also very picky with food and obviously not an easy person. So I’m happy, she still sticks with me and I’ll happily cook for her
