iMessage Spoof or Spoil?

[foolfully]

My girlfriend got an imessage from my email account and thinks it was me but it wasn't me.

I think someone may have stole my old 3GS, guessed the password and is using it on wifi. They must be seeing my imessages people send me like my iPad does and they meant to reply to someone else but they got confused when someone else replied to me and the imessage was displayed on the stolen iPhone.

Is there anyway I can check all my iMessages to see what they have been sending other people?

How can I disable iMessages only on the stolen iPhone - change account names?

Is there an iMessage history so I can see if they messaged anyone else who has an iPhone?

If you sold or had you iPhone stolen previously and iMessage was set up on it then there isn't a way (that I know of) to get rid of it. Time to change your Apple ID.
