Every time I sign into FB from a different computer I get a screen that asks for my computer name? FB then sends me e-mail (to the registered e-mail address) that info. Now someone can use ANY name for the computer it wants, so that may not help, but you would KNOW that another computer connected.
This is a typical message I get :

If you DID NOT get one of these, then I'd assume someone used YOUR computer. Otherwise I'd think you're supposition is wrong. Whomever you had that private discussion with 'leaked' it to someone else.
I could be wrong though... it could have been the other person whom you had the conversation with that was compromised?
