Why my ex suddenly contact me again?

Me and my ex met on an app. We've dated almost for 3-4 months and ended 2 months ago. (We were not in a relationship!) He said he doesn't like my personality... and I got dumped by him :'(
Yesterday I got message from him. If he still has feelings for me or if all of this is completely about having sex? Or maybe he looking for Christmas dating partner lol
