Express your ideas and truths. They matter and that will also safeguard against resentment in your marriage, towards the kiddos and other relationships but then be willing to accept the outcome no matter which way things go. How? By praying about it first then trusting the results to God! If you end up not getting your way remember that you gave it to Him. That will make it easier to just "let it go!" Ephesians 4:15
