My ex texted me a day after he broke up with me like nothing happened?

A day after he told me he doesn't want to hurt me and it's better off if we'll end this, he texted me, like old pictures on Facebook, told me how his nephew misses me and sent a video of his niece telling me she misses me and to come over. I asked him why didn't he tell his family we broke up. He said "I don't know, I just told them we had a fight".
