TS2755 How to a delete iMessage from my Apple ID?

Question

Hi there,
I recently moved back to Blackberry, but when people text me (from iPhones) they still go through iMessages first (the blue ones). Now a friend of mine seems to be receiving these messages on his iPad, I don't know when I signed into it, but apparently I did. Due to him being not very trustworthy, and refusing to do it himself, I changed my Apple ID password so in theory for him to receive any more messages, he'd have to sign in with the new password right? Despite that, he sent me another message after I'd done that saying he'd received another message from my mum and quoted what it said. It was exactly what she sent me.
I do have an iPad but they don't seem to be going through to that, in any case, I'd rather my number and any email was just removed from any association with iMessage at all because I never use it, I don't want to use it and I don't think I ever will.
Any help would be much appreciated.
Nick

How/why do you want to remove them from your account ? e.g. if you are selling or giving a device away and want to unlink it from your account so that the new owner can register it to their's then you can do so via your support profile : https://supportprofile.apple.com/
A device or computer will only become associated to an account, and appear in the 'manage devices' section, if you use iTunes Match or automatic downloads on it, of if you redownload the account's past purchases on it (if you don't have any associated devices/computers then the section won't show). Have you done any of those ? You could try redownloading a past purchase on a device or computer and see if that section then shows with that computer/device listed (but if you do then it will become associated for a minimum of 90 days).
And for the hidden purchases, have you ever hidden any ? You could try hiding something and see if that section then shows : hiding and unhiding.
