Friend hates me please help?

He's using you like a convenience store. Always runs to you in the darkest moments when all other stores are closed. He doesnt reciprocate the help you give him. You dont really need him. But please dont offend him. Im saying this because he knows your most unspeakable and darkest secret. He doesnt seem nice and he could use this info against you. So the next time you meet just say sorry. You dont need to say your excuses, just apologize. I'd still bet he'll be running to you the next time he gets his heart broken.
