The process of custody modification is not simple or quickly done. The situation you describe is not going to be adequately addressed at a review hearing. You will need to consult with an attorney on filing a motion to modify various aspects of your divorce decree. Your question is so fact-specific and unique to your decree of dissolution that you should be certain to have a copy of the Decree and any subsequent Orders modifying the Decree to discuss with an attorney.
Additionally, you should be very careful in dealing with your children's attitudes towards their father. The Court system is very sensitive to one or the other parent speaking poorly of the other to/through the children. Also, it is a delicate balance between wanting to protect one's children from a difficult or abusive situation and one's responsibility to encourage and facilitate the children's relationship with their non-custodial parent.
