Basically, you can’t win people over if they don’t want to be won over by you. It’s not that they don’t want love or devotion; they do, but just not from you. They have invested their emotions somewhere else. You want to be their pet but they only see you as a dog, a watchdog perhaps. You are attached to them but they aren’t attached to you. From you, they get everything too easily, so perhaps you’re of no value to them. Ironically, if you don’t wish to be taken for granted, if you step back, they become resentful or angry.
