OK so like I said in chat, I'm going to put a biggest fattest silver lining around this and assume it is all 100 % genuine. That still means she doesn't want to have anything to do with Ralph. Cos if she did and honestly thought they are friends (Ralph has no friends, people are purely instrumental for him) she wouldn't have to use a blank SM account with no personal contacts, that nobody on Earth knew exists to say it.
She could have said this in her own way, with her own words on IG or FB if she honestly felt bad and wanted to make it up to him. This is Deni alright, but this is meant for Ralph only, well, and a-logs I s'pose. So yeah it is 100% true that she wants absolutely nothing to do with Ralph. And Ralph, knowing this, sweethearting her is just plain creepy behavior.
