If the screenshots are as fake as he claims and they are in fact still together as a couple as it appears by the way he’s talking, then why doesn’t Dijana herself release a statement - even just a short written one - to clear it up?
Maybe she’s letting him stew in his own mess. Maybe she’s weighing her options. Maybe because of any police investigation she can’t say anything?
There are so many things that don’t add up about this imo.
