Although you might start out the month talking to your love about anything and everything, as the December 19 approaches, you might find yourself losing communication steam. This might be intentional, but it may also be due to feeling more misunderstood by your partner.
As a result, you might take the hermit approach and decide it's best to keep quiet so that you don't risk unnecessary arguments. You'll benefit from this low-key approach because it will allow you to reframe expectations you have about your relationship direction. After December 29, you'll be able to implement what you've discovered.
