If the parenting plan adopted in your divorce decree does not deal with the question of relocation you can file a motion with the court to ask that the relocation be prevented. That will be decided based on the best interests of the children. The obvious impact on your involvement as a parent is one important fact in deciding what is best for the children, but that decision does not involve your "rights". The issues relate to the children's rights - not yours.

You can use the courts to intervene in a case like this, but a temporary injunction is not the usual way to do it. If a spouse wants to take children out of state for more than 90 days, and the other parent has any custody or placement rights, she must send you a notice sixty days in advance, with detail about where she is going to live and when she is moving. You have a short time (I think 15 days) to file with the Court an Objection to the move, and request a hearing. Do not let anytime pass without taking action. Find a skilled family lawyer as soon as possible, and today is not too soon.

You should be able to. The law in Idaho is that neither parent can move out of the state with the children unless the other parent agrees or it is in the best interests of the children. If you are able to take care of the children here, then just that she is going to get a better job should not be enough. When you file your motion for the injunction, attach a copy of whatever she sent you saying that she was moving. If it is only oral, you can go with that, but written is better if it is available.
