I'm sorry, I just don't feel comfortable giving advice in this situation as I am barely 18 and have little relationship experience (I'm asexual). I can only give general rules and tell you what my experience has been like. Like I said, you should talk to your husband and his doctors, as they're the only ones who can describe what's going on in his head (and hopefully the doctors will help you call out his bs.) I will say that it's not uncommon for people to misuse their diagnoses, I've seen it myself... Sorry I couldn't be more helpful.
