This is a great point that bears repeating. If you don't trust your coach, he shouldn't be your coach, because it won't work for either of you. Like Mike said, do a bit of poking around and see if this coach is someone you can trust and you're just not yet comfortable with him, or if he legitimately has no business telling you what to do (both are entirely possible).
