When someone tells you, “I love everything about you” that should be said once and that person should mean it from that moment on. You don’t want someone who says that, but the second you do something that isn’t up to par, you feel like a failure. If they truly loved everything, they would even love your mistakes, your flaws, everything. That is what that phrase means in the first place, “I love everything about you”, Everything. As in all of you. Which includes sometimes loving you even through your mistakes.
