Sadly I think we know how this will turn out from her odd tweet last week, where she pretty much made clear she was hitching her wagon to ADR (especially showing off the Papi tattoo on the Graves show) rather than WWE.
This really should be the wake up call for her not to throw away her career, but it's not looking hopeful. Ultimately this is a girl who missed out a lot of her teen years as she was in the ring, so she's acting out. I get the feeling she's another Davey Boy in the making - he did the same and it led to him overcompensating later...but Vince ALWAYS looked out for him, giving him chances. I get the feeling Paige might be the same but more from Hunter.
In itself, the relationship isn't the issue unless it's a toxic one - ADR could very easily be doing right by his family and just moving on with his life with Paige, that's their right. But it's clearly impacting on her negatively... the "arrest" wasn't that, but she apparently ran across an interstate after an argument... Sadly it seems that Paige is a very emotionally immature and possibly impressionable young woman... If the bosses could have picked a WWE guy for her to hook up with, ADR wouldn't have been that guy...
Even if she ends up leaving now - I think WHEN it all ends with ADR and she sorts her shit out, they'll welcome her back, as long as she steers clear of the porn route...
