I question the use of the word love here. If you're seeing attributes in your partner that don’t exist then you are not in love with your partner, you're in love with someone you pretend or imagine your partner to be, or wish they were. I would call that puppy love. Like when you adore a puppy because it's so cute and a little awkward, and you imagine you'll be besties forever and ever. And then you're taken by surprise when your favorite shoes get pooped on or half-eaten, and when that cute little thing grows to monstrous proportions, wanders off regularly, constantly barks, burns through your paychecks, and completely ignores your every command.
