Detachment is stopping co-dependency. This is where your spouse affects how you feel emotionally - because you are dependent on their words and actions. IE You ride a rollercoaster of emotion due to their actions and words. Detachment is therefore stepping off this ride so you can be you without attachment - like you were before you met (the person she fell for). It doesn't mean not communicating but it does mean not pursuing. Let her come to you if she wants to. Stop all chasing for any form of attention it is a sign of co-dependency/being needy. It's really unattractive. It will push her further away.
