Your W isn't thinking of leaving because you don't do enough dishes, and all of a sudden cozying up to her family and watching to see how she reacts comes off as disingenuous and is a form of pressure on her. Right now you're acting out of fear that any little thing you do wrong might be the final nail, but you can't live the rest of your life walking on eggshells and attempting to be perfect. Like the others said do what's right and do your fair share...but do not become a man running around to grant her every whim. Not only is it unsustainable but it's also unattractive.
