Hard to say. He could have dumped her. They could have mutually agreed to "cool it for awhile," based on your recent pressure (this would be my personal guess). Or she could have broken things off with him, fearing she's losing you and/or fearing her financial future as a divorced woman, and just doesn't want to give you the satisfaction of telling you that (how can you admit you broke off something that never was??).
WHICHEVER it is, it really wouldn't change your strategy or tactics any.
