Knowing a parent doesn't want you and still makes that apprent is heartbreaking but also leaves that child not only scarred but also too aware of that human side at an age where they shouldn't be.
I am glad that they have included this into a marriage. Where it is simply given that you will have children and want them. Even though people do want their professional lives they should also want their personal one.
Your professional life is a job. A job that you come home from not come home to. If you lose that you can get another, who knows if you get another reason to come home.
