Is my ex boyfriend in a rebound relationship or did he already move on?

So he got together with a co-worker a week after we broke up. A few weeks after that they are basically living together and spending every single day together. Not to mention they are co-workers from the same shift so they see each other at work too. When he broke up with me he deleted me from Facebook a few days later "because he couldn't sleep" which is true cuz i was on all the time and he kept logging in and out. While we were in a relationship he rarely used Facebook to post anything. He just went in there and liked pictures and messaged relatives back home. I got curious and i checked his Facebook page :/ NOW, he's constantly uploading pictures of them together for public view,(even though all his other pictures of himself and family are private), posting cute things like "She cooked me and my bro dinner, my girlfriend is awesome!" and he's constantly posting "Having fun with my GF at golden coral" or other restaurants. They have known each other for a month when he broke up with me and they have been dating barely for two months. I know their relationship started out extremely rocky because my sis works with them and she saw the fight almost everyday.He cut contact with me exactly one month ago after he begged me to see him one last time in person. But during their first month of the relationship he kept calling me and asking me how i was doing and sometimes he would call me to tell me the guy i was seeing was just using me and that he still cared for me as person but he didn't love me. THEN he goes into a jealousy fit when i told him i didn't care since i was seeing someone else. Saying to be careful because he would kick any guy who fucks me over and take them on a "drive to the desert". BUT then he practically shoved in my face his "GREAT" relationship with this girl, saying he was happy and even if they constantly fought he enjoyed every moment of it because "he like her a lot". Did he really move on or is he on a rebound?
