PLEASE HELP...What did he mean by saying that he alters what he says around some people? (below) BEST REWARDED?

Are you asking if he is lying to you? I doubt it. I think that he feels comfortable enough with you to tell you about altering information. And I don't think that even means "lying," although you would have to ask him what he meant when he said that. He probably doesn't tell everyone everything about himself, and maybe downplays the things he has and what he does. You say that he is always sweet, and liars are not usually sweet. Go with your instincts with him.
