Only replying to this to hopefully, finally put this to bed: Yes, it's just gossip.
The reasons I believe this keeps coming up are as follows:
1. Her changing her camming schedule
2. When she would take breaks or vacations, people had trouble understanding that she would do so alone
3. She has a handful of extremely parasocial followers who openly and publicly post about their plans to "marry [her] some day." Some people have surmised that the above 2 reasons, combined with these guys' public simping (including giving her egregious amounts of currency through MFC and likely OF of Fansly as well), that one of them must actually be involved with Ema on a personal level.
Of course, if you stop and actually use your brain box, you'd realize none of that makes logical sense, but gooners aren't always the most cerebral people.
