Do you owe your ex answers about your current life?

I was listening to the radio this morning that does EX files and they had a guy on talking about how he still follows his ex gf on instagram. She posts pics which he has studied enough to notice someone is being cropped out. He confronted her on the radio and she admitted to seeing someone new. He was upset because it was “only three months” and why she was hiding the new guy. She said she wanted a more private relationship than what they had on social media.

Do you think you owe your ex answers about how you’re living your life after the breakup? I think this guy was absolutely ridiculous and came across as pathetic.
