Love isn't a state of perfect caring. It is an active noun like "struggle". To love someone is to strive to accept that person exactly the way he or she is, right here and now.
...in our culture, it has been aptly observed, "we are never as kind as we want to be, but nothing outrages us more than people being unkind to us." In his stirring Syracuse commencement address, George Saunders confessed with unsentimental ruefulness: "What I regret most in my life are failures of kindness." I doubt any decent person, upon candid reflection, would rank any other species of regret higher. To be human is to leap toward our highest moral potentialities, only to trip over the foibled actualities of our reflexive patterns. To be a good human is to keep leaping anyway.
