Be a healthy parent. If you think alienating a parent from their child is acceptable behavior please seek professional help to work through your confusion and misunderstanding. Let someone help you understand that you do not need total control over ANYONE and you will never have that, anyways. Kids are people with rights.
"You are meant to grow old with your spouse, not your children. Don't treat your child like your soulmate." I love this, I was taught this before I was married and its how I do things. My marriage is great and my kids feel safe and loved within the house, but they know spouse comes first.
