Not treating your spouse correctly is your biggest mistake,
No matter how you treat your spouse, you will be a role model for your children’s future; That is, they will treat their spouse in exactly the same way. If you treat your spouse incorrectly and are constantly arguing, they will do the same. Children “follow your behavior” more than you advise them.
If you treat your spouse with respect and love, you will show the value of family to your child, and they will feel more secure than having a “safe haven” in this wild world.
