Parenting plan gone bad

For months I kept telling my husband, just wait till we have a court order, she (marie)will hang herself with all the games she plays. Having dealt with numerous witholding the children, denying contact, refusing to communicate and coparent, a child abuseninvestigation on mom, I really hoped the court order would make her(marie) shape up and start actually thinking about the best interest of her kids. Boy was that a big misconception! From the day we left court and they (husband and marie) attested on record to the paternity action and parenting an was in the kids best interest, the extended reign of hell began to worsen. Mind you, pretrial conference/mediation resulted in my husband being backed into a corner and basically told to settle with the parenting plan terms that she (marie) had put in the petition. So, now goes the daily struggles with getting her(marie) to follow the parenting and communicate and coparent with us. The first visit scheduled with dad began the start. Mom (marie) said that my husband had to drive to pick the kids up from daycare or he couldn’t have them. We had to remind her that meeting at daycare occurs whenever possible, otherwise it is done at the local pd between the parents homes. After being told we bullied her into meeting at the pd, she showed up. This was the first of almost every week argument argument where the kids were going to be transitioned at. Not sure exactly why she doesn’t seem to get that the court order is what is law and must be abided by unless BOTH parents agree otherwise. We keep telling her to talk to her attorney or have someone read the plan if she doesn’t understand it. Usually results in dad being called a bully, intimidating her(marie) or not putting the kids best interest first. Maybe one day she will understand what’s written in the plan for transitions but until then, dads response to every arguement about transition will be,” follow the parenting plan”.
