Because of they divorced it doesn’t mean they stopped loving each other, even they don’t love each other it’s normal that he keeps that picture, it shows how mature he is
So he still loves her? If yes then i wld get why hed keep it dince he cant move on. But if he doesnt then even if put away the pic id think he mature no matter what
Him keeping the picture doesn't mean he still haven't moved on, he still loves her but that doesn't mean he'll get back together with her when a chance arise. It's just like keeping your photos with people that you aren't friends anymore, you still appreciate the memories you have with them but there's a big chance you won't reconnect with them anymore.
Taht depends on how u left off the relationship...but thats still kinda weird in my opinion
Bothered me how he still had a pic of his exwife and him, hope he took it down after they officially started going out
