Remember, getting a life activities are not to get her attention. They are to get YOUR life back on track and to stop you from obsessing over your wife leaving. Right now you are acting like you are a footnote in your wife's story. STOP IT. You are the main character in your own story. Start acting like it.
Many of us have been there. The aching pain in the gut, the tears, etc.
Become someone you've always wanted to be. Practice Resurrection.
The more you become this person, the less you will worry and obsess over every email, text or communication you have with your wife.
