If I discover that her EA has turned into a PA, that would likely be a dealbreaker for me. The EA partner lives 1000 miles away, so it’s unlikely to turn into a PA anytime soon.
Hi Dbx80, she's in a hotel room even though she doesn't mind seeing you nearly everyday, she says it's okay for you to date (which implies the same for her), and 1000 miles is only a weekend flight away. You know your wife, but to an outsider, your situation sounds perilously close to a PA.
I hope it doesn't come to that, of course. She did say dating's okay "as long as it's not physical", which implies she realizes getting physical crosses a significant line in the sand.
