First of all, your ex is wrong to tell you that he will arrange it with the kids. He must arrange it with you. Your divorce judgment probably has some provisions about custody and visitation. Depending upon what kind of visitation he is allowed, you could go back to court with a Motion to Modify his visitation right now to just a few hours at a time, or at lease supervised visitation, since he has been out of their lives for so long and the children should be given an adjustment period to get used to him again. This is not unreasonable to ask.
