You'll never change your life until you change something you do daily. The secret of your success is found in your daily routine. Maybe adding a daily habit of more love with your child might make a positive change for both of you.
Letting go doesn't mean that person is no longer in your life--it means--you simply don't care what he/she thinks of you any longer. AND you have quit letting he/she take away from your happiness.That was my happiest moment!
