For me if there was an E&V situation with the non shutting down of the Elsbobs rumours, I think I would be put off E&V. It all feels a little press grabbing, trying too hard to stay relevant.
Edit - to add I did take a look at Ellie’s PR team - a fair few love islanders etc on the books. I’m not a fan of that style of PR.
If Ellie and Vito were together and didn't shut the rumours about Bobby I doubt it would be because they want the press attention, Ellie seems to have been very uncomfortable with it and there sources saying she was upset and Vito practically disappeared that week. If they are together I suspect Vito would be very keen to keep it private at all costs I got the impression the attention and especially post relationship press attention with his ex took a toll on Vito.
I'm sticking to my theory that they decided not to act on their attraction to one another. And maybe that's why they enjoying touching on stage it's safe place to indulge in that attraction without it going further.
If there is/was anything with Bobby it's just a bit of fun that got out of hand. Maybe the speculation killed whatever was going on.
