You shouldn't need someone you trust more than yourself to slap sense into you. You should view someone whom you trust strongly (but less strongly than your own thoughts) arguing hard as an indicator, even if you disagree with them. You should be able to ask "Why do we disagree", and trace that back to (hopefully) some simple but core value difference, like "I like hotdogs and they like hamburgers".
