Ask her to stay

"Stay," you beg her.

Robin looks torn. "I can't. I have to go to work."

"That's fine. But come back after that. Leave your husband."

"I can't. I want to, but he's good to me. I don't want to leave him alone," Robin says. Contrary to what she said, she's let go of the door and taken a few steps towards you.

"What if... what if I could find someone for him?" you ask.

"That would be... okay, I guess. But how? Are you going to pay someone?"

"No, come with me." You lead Robin into the den, sit her down and then start to tell her about the magic rings and how you'd come into possession of them. She's speechless at first and you can tell she's skeptical, so at the end you demonstrate your powers to her. Invisibility is the easiest, then you stop time with her and teleport you two to the Louvre in Paris where people are frozen in motion. She runs around in wonder and then she looks at you.

"Wow. This is real. I honestly thought you were a little crazy," she says with a grin. "But why all this? Why show me? You could just make me stay with you with your rings."

It's weird standing in a public place naked though nobody can see you or move. "Because I like you and I want you to stay because you want to."

Robin walks around the museum while thinking about what you'd just said. You follow at a distance, giving her some space to process everything. Finally, in front of the Mona Lisa. she turns around with a cryptic smile like the famous portrait.

"Okay. I like you too. Let's do it. But we have to find someone nice for my husband."

"I have somebody in mind," you say as you grab Robin's hand and teleport back to the mansion.
