Second, don't deduce your opponent's intentions from your own fears. It is common to assume that your opponent plans to do just what you fear they will do. Third, avoid blaming your opponent for the problem. Blame, even if it is deserved, will only make your opponent defensive. Even worse, your opponent may attack you in response.
Blame is generally counterproductive.
Fourth, discuss each other's perceptions. Also, such discussion may reveal shared perceptions. Acknowledging shared perceptions can strengthen the parties' relationship, and facilitate productive negotiations. Fifth, seek opportunities to act inconsistently with your opponent's misperceptions. That is, try to disappoint your opponent's worst beliefs and expectations about you.
