Thanks Zeldman for sharing this:
And then, bang. Your kid is laughing ecstatically in a seemingly utopian environment you did not provide for her and you are not part of. The easy adult social interactions that are unfolding belong to your ex’s new life, not yours. You are watching your family move on without you, you are discovering all over again, as if for the first time, that your family has exploded, your wife does not love you, does not need you, the world goes on without you, this is not my beautiful house, this is not my beautiful wife.
