While I do believe he has something to hide....there are other possibilities. Like maybe he is feeling, for whatever reason, that he doesn't really have his own space or individuality anymore and just the simple act of asking makes him repel it. For example....have you ever been contemplating doing or saying something but the second someone TELLS you to do it you just don't want to anymore? Like I want to wash my car cause it's nasty....but the second my bf says "go wash your car" it flips a switch in my head and I just wont. I'm overly stubborn so that's why I'm thinking that could also be possible.
