What is the training life like for a wife to a PJ husband?

My husband is joining the air force for Para rescue. We have heard the training is about 18 months and during that 18 months we will not be able to live together and that he will not be stationed anywhere until he is done with training. Does anyone know if this is true and also, how dangerous is being a PJ, his recruiter is telling him there hasn't been a death in that field since 9/11. As much detail on this subject would be greatly appreciated it. I just want to know what I have to prepare for.
