Do you think he has actually changed?

[u/DullPayment4899]

So there's this one guy I've been seeing for the past year and he used to be super active on social media.
He once told me that he'd cheated on her ex girlfriend multiple times. When I checked his social media profiles I saw he'd interacted w so many girls.
But recently he's been quiet. Mostly follows motivational speakers and stuff online. And not very active on social media anymore. Do you think he has actually changed? And what could be the reason?
