((((Adhdinlove)))) I'm sorry you're struggling. The only way to know for sure if he has ADHD or not is to convince him to get a proper diagnosis... the problem is, you can't force him. He has to decide whether he wants it or not. As far you know, he may have already have a diagnosis. So what you can do is just suggest him, but the final decision is up to him. It's possible that he may just decide to end the relationship for good. In that case, I suppose you'll just have to move on... I'm really sorry
