Thank you for apologising. I can't comment on whether you have applied for the "wrong" sort of disclosure, because from my experience in SS it is Clare's Law that is suggested within safeguarding meetings - perhaps because it's more accessible. I don't know the rationale for why multiagency professionals (including the police) tend to favour Clare's Law.
The fact is, you were proactive and that shows that you care. That's really positive.
I think you've left some unanswered questions around why you are now suggesting he had done "nothing wrong" when he triggered your gut instinct to request the disclosure in the first place. I would also wonder whether his behaviour has improved because you have made changes to your own behaviour to keep the peace - but perhaps you don't want to answer that.
Hopefully you can see that those saying it isn't a checking service are responding to things you have said, laterly, now that you know that his Clare's Law disclosure is clear. You didn't do it routinely; you were prompted to do it by his behaviour.
Please don't see people trying to help you as being an attack. I'm sure some responses haven't been pleasant to read and that comes with the territory of posting on here, unfortunately. The vast majority of responses fundamentally have your best interests at heart.
Hopefully you can understand that by posting this, it's also brought up feelings for people and their own experiences - which may explain why some of the responses are coming from people who have experienced abusive behaviour. It's actually quite a traumatic subject and hopefully you can see why some people are questioning your shift in reasoning.
Sorry for the essay. Honestly do wish you well.
