Strange breakup

Simon
Okay so last night by boyfriend well ex boyfriend was making plans for me to go the beach with him and his family and telling me how beautiful I am along with saying how adorable I am and that he's excited for me to meet his family. But this after noon he messaged me on snapchat of all things asking if we are still dating I said yeah and he asked if I still want to and I said yeah and asked if he still wanted to and he said I quote " nahhh it's not really working out" does anyone have any ideas of why he won't give me anything other than it wasn't working out anymore.
