I am sorry you are in this position, I dont think a court would not let you have visitation rights to your
children unless you have been abusive to them,
Children do need both parents in their lives, I believe many studies have been done showing that children do better with both their Mom and Dad having a positive participation, if your wife has a problem with it and you know you are a good Dad fight for your rights and know that your children will be glad you are in their lives.
