Yes, exactly. Questions asked above about "why wear it" and "didn't she say" are plausible scenarios, but there is still nothing definitive. We've not seen her with anyone else. She didn't even mention another man. If she were going to see someone, it could also be a woman, hermaphrodite, transsexual, etc. And meeting with, say, another woman also doesn't rule out the possibility of her cheating on the MC. The point is, we just don't know. I'm not saying it's not possible; I'm only saying to give it a chance to be revealed.
