He still use our couple photo as his profile picture.

Ok, well it has been around a week after our break up. He unfriended me in fb. But now, he still using our couple photo as his profile pic and cover photo in fb, include me. Yeah, even though Im doing the no contact rule, I still havent change it. As in the rule, I didnt contact him since that day.
But Im wondering why does he still keeping the pic? Im accepting every opinion. Thank you so much.

Honestly from a guys perspective he still wants you and trust me he looks to see if you have changed yours because it basically says you have moved on.
Right now his pride is telling him " don’t call her, don’t" but he is dying to, so keep doing NC and he will call you or text you. Right now his ego is busted and is trying to build himself back up.
If he sees you change it then he will change his, so if you want him back don’t change it
