Criticism - is general and includes blaming your partner. Usually it will include words like "never" and "always." Everything is your partner's fault.
Withdrawal - occurs after excessively demanding, hostile or nerve-wracking relationships have become unbearable to handle; includes ignoring, not caring, apathy. One tends to withdraw from the emotional situation to avoid being hurt again.
