Why is he inactive on social media now?

Anonymous
Me and my former boyfriend (over 2 yrs) ended things 3 weeks ago
We were both big social media people
We liked to post pictures every week

After we broke up, I deleted him on all social media

But I still post pictures often

But today I was curious
I saw his instagram and the last photo he uploaded was 3 days after we broke up
So about 3 weeks ago

Why did he become inactive now?
