Emotional thinking is the crafty and conniving enemy within. It operates under a cloak of apparent logic to drive you to continue some form of engagement with the narcissist and thus maintain your addition and heighten your emotional thinking further, leading to sustained interaction, the inability to move forward and furthering the pain, allied with feelings of anger, pain, misery and frustration.
Curbing your emotional thinking is essential and thus you must recognise it before you lose insight and then reduce it through ceasing or preventing engagement through no contact.
Emotional thinking will hijack your empathic and/or narcissistic traits and use them against you. It might be by causing you to keep wanting an explanation from the narcissist as to why he or she has done what they have done (Truthseeker), it might be remaining with the narcissist because you perceive they cannot manage with out you say through a health problem (Guilt and Compassion). It might be causing you to go to war with the narcissist (Pride and/or Justice), to remaining engaging owing to the presence of children (Decency) or thinking that love means taking the rough with the smooth (Love Devotee).
