ADHD husband creates situations that are not there

Hi guys. I need some help. I have been married for a year and my husband has ADHD but is unmedicated. He drinks every day, too. Not only is he unpredictable, like I don't know which version I'm getting that day but also I have noticed he created situations in his head. He can be on a work call (we work together) on speaker and he will make comments like "did u notice this person saying "hey" with an attitude? " and no it was a normal hey. If we go out to dinner or have guests over he accuses me of looking at men in a certain flirtatious  way or that we exchanged looks or comments flirting. It's all in his head and he believes them wholeheartedly. That's why I think it's more than jealousy, it's like his hyper focus is driving him to schizophrenia. Imagining things and exaggerating experiences. When I try to explain thing he won't listen. Has anyone experienced this before? And if so, how have u handled it? It's draining me and driving me to depression
