Why After 2 months apart my ex is posting our fav place, drinks, and songs in his ig?

So he is posting pictures from our fav place,, songs that I liked, and photos of drinking our fav alcoholic cocktail...
He wasn't into posting things like that before... Why he is doing that? and why after two months..
