Some additional thoughts...

This thread has some good information about safely reducing or withdrawing from medications, including why doing so abruptly can bring on a resurgence of symptoms: Matters to Consider When Reducing or Coming Off Medications

In that same thread, I also talk about the need to develop a Support Team and a Support Toolbox. As a possible suggestion, maybe it would be helpful right now for the two of you to split that task. You could work on developing a support team for yourself and he could work on identifying the things he finds helpful to him.
