Batman has always been taking help from others, it's in his psychology. Anyone who lost their entire family at such a young age would strive to create their own, even if he does in it a bizarre way. He pushes people away because he doesn't want them hurt like his parents, not because he doesn't trust and thus is forced to know their every strength and weakness, devising dozens of schemes to take them down because he's totally the smartests guy in the world.
It's because when you dig down real deep into who he is, he's someone who cares deeply about his family, his friends, and ultimately everyone who swears to protect. He may sometimes act like a dick, but all he's really doing is showing how much he doesn't want to lose another person.
