Very possible. Personally, I would find it odd and disturbing if some guy just kind of followed me around on social media. I was trying to give the guy the benefit of the doubt. But you may be spot on here, that she's just withdrawing, and probably upset that a place she may have seen as a sanctuary isn't one any more.*
*True Story: I enjoy lots of social media and have a relative who follows me around. This is not a person I want to hang out with. So I mute this or that, keep this relative off lists of followers I communicate with, etc. I would block them entirely but don't out of respect for my mother. If my mother wasn't in the picture, it would be a different story.
And every time this relative catches up with me online, I sigh, adjust settings as well as I can, and feel a bit violated. Again.
This person isn't nasty and they're not dangerous. I don't hate them. But they're just overbearing and we have little in common. I don't want to spend time with them beyond the minimum. At family gatherings, I do not seek out this person.
The only reason there's any sort of connection is my respect for my mother (and for this relative's mother and sibling, etc.). If this was someone I met at a party or a class or whatever, I would never give them my personal info.
