There is a way...
Every time your ex-wife does not allow you to see your children, or gives you a hard time, file a police report. The police will say that they do not get involved because it is a civil issue; just let them know that you just want to file a report so that there is a record of it. Later, this report will hold ground when you propose it to a judge. You can also contact CPS; file a report and let them know that you have a concern about your child's well being. They may say that you qualify (child) for an investigation or may not. There has to be some very serious things going on for them to consider an investigation, i.e. physical abuse, malnutrition, lice, smells, etc.
Keep a record of everything your spouse tells you that are negative. Keep a record of everything your ex- spouse's new husband, wife tells you.
When you build up enough information files for a court hearing (Suing them for contempt). The first time, the Judge will just slap them on the wrist. The second time it happens, look out, the Judge will put them in Jail or revoke their license. This has happen to me (male), and my ex-wife did not allow me to see my sons. My ex did not report where she lived and her new husband would harass me.
Never respond to your ex or rebuke them, just let them speak their minds, and later you will have control of the situation.
I took her to court and found in her in contempt. Now, I'm able to see my sons.
Patients and smarts- they work.
