My question involves a child custody case from the State of: Colorado

Quick summary, my husband seperated in 2009, divorce finalized in 2010, parenting time finalized in 2011. It was a messy messy situation, husband was accused of all kinds of things. Husband's ex-wife still has restraining order on him. My husband got joint custody of his children in 2011.

In 2012 husbands ex wife questioned him if he would fight her on moving the kids out of state, he said no, as long as she didn't fight him on visitation in summer holidays, etc. I am the new wife and when he told me about that, I put in for a job out of state, that I had received and turned down a year before since we got joint custody, so I got the job, his ex wife didn't move, I move to my new job, my husband stayed until he got transferred and him and his ex decided to be civil and agree to a plan and have it filed in court. Ex wife kept putting it off, we have no money for an attorney, the day before my husband transferred to new state, his ex said she just wanted to keep it out of court. We agreed on extra amount of child support, visitation, etc., but nothing signed and in writing.

My husbands ex wife is and his children are now moving approximately 4 hours from where the court is and the childrens home town, my husband has no problem with this, but still nothing is filed in the court.

As I said my husband's ex still has restraining order on him, but now acts like she loves me and is good friends with my husband, but continues to procrastinate having it removed. She come to our house and visited when we went for holiday to visit kids, she asked to ride places with us, she obviously is not afraid of my husband.

I know I am all over the place with my post, but I am worried about the whole situation...

1. Can my husband get in trouble for moving out of state, he is not the primary residence or custodian of the children, is there something we need to do fix the situation.
2. They agreed on a visitation plan and this Christmas is the first time kids are scheduled to come so we will see if it happens or not, but now I have friends telling the ex could be vendictive and call police and say my husband took the kids without permission, and if something like that happened he would be in big trouble.
3. The restraining order, can she really get away with having this r.o. and breaking it herself, it seems not only my husband would be violating the r.o., but she is too. She is supposedly going to file to have it removed this week, before she moves.
4. If we mention court or attorneys to his ex she flips out, so can we continue to leave this out of court or could it backfire on the both of them???

Please help.

Thanks
