We’re talking again but why would he want to start his social media accounts from scratch and erase our old memories and photos?

So me and my ex bf hav stared talking again.

He just broke apart from his other gf.

But he deleted his faces book and social media’s with all our old relation memories and photos but also of his ex.

He made a new social media accounts and started again. But all photos are gone

If he wants to go back together why would he erase all our memory’s?
