Stop setting a precedent of supervised visitation immediately! Get a father's rights attorney. Get the kids to an alienation trained therapist that can write a report and testify. If your fiance & you are serious do it, make sure you get the prenups in place. Motion for primary custody based on your new marriage-thats a major change justifying custody re-hearing. Include motion for contempt for alienation and use her motions as evidence of her litigious behavior. Get yourself a custody eval right away. Motion for supervised visitation for her, psych eval for her, social investigation, custody eval. Get a motion to compel counseling for the kids and get them to the alienation trained therapist before she gets an order preventing you. It'll cost her 25K for openers if she wants to play that game, and the kids need an objective voice telling them what she's doing. Your attorney will know how to make at least half of that come to pass. Sounds like she's angry you've moved on and will hurt the kids to get at you. Rotten thing todo, be careful and don't play nice back.
