if you tolerate too much half-heartedness, it’s probably because you’re half-hearted. As in: anxious and ambivalent, looking for reassurance. As in: bored, along for the ride, not really sure about your own feelings and opinions. As in: external locus of control vs internal locus of control. You probably don’t have anything in your life that really tethers you to yourself—you don’t have conviction about what you love, so you’re hoping that someone else will provide you that certainty.
