First identify their personality type. Understand their past and see if they are an introvert or an extrovert. I had to do this with my boyfriend. They look up communication tips for that personality type. Introverts need to recooperate from people. Identify how they view relationships. Are they old fashioned or contemporary or both? See how they were raised. We are a product of our environment, uf they are in denial about bipolar then well treat them with kind safe words. Not on egg shells.
