Get a good book, make sure you are ready to go to bed BEFORE her. I strongly suggest that you do not sleep "on your side" Pick the middle. Claim you space. You are a CALM, confident alpha male that sleeps wherever he chooses. She can choose to sleep in bed with you.
Listen and validate. Listen like you have to memorize everything she says. Listen like there will be a test on it tomorrow.
