I agree with much of what you have said. However, single people have also had to set aside desires of the heart. Also, in my teens my home was a happy place but I didn’t necessarily feel like I wanted/needed to share with my parents the anxieties/challenges I sometimes had.
God's wants us to learn both sides of this situation. So we have stop to blame things, people, principles, doctrine, policies ect. And practice Love because this we can do, the rest is in God's wisdom. It is so great to see parents and children that are in this situation or any others situation Love and respect one another not matter what. In the beginning and end everything is about learn to love . This life is a time to prepare to meet God. Love is the ultimate law.
