Cognitive behavior therapy is secondary to and rarely works without medication and is usually to keep them ON the medication. Delusions are a powerful distortion of your core beliefs as a result of abnormal brain function. The chemistry of the brain needs to be managed first.

Professional experience?

My point was just that given the thought patterns that would be formed from such behaviors, even if medication alleviated some or most of the problems, there will probably still be some issues that need to be dealt with. The other issue is that it's difficult to tease apart morbid jealousy from obsessional jealousy (and those two from "normal" jealousy) and currently I don't think there are any guidelines to be able to do that, so finding the cause is not terribly easy as morbid jealousy (as a psychosis) would probably need medication, whereas obsessional jealousy would need CBT (and perhaps medication to help the process). And delusions aren't necessarily caused by abnormal brain function, or at least the last time I read up on the topic there will still a number of different approaches to the nature of delusions..
