I don't blame her. Compared to her contemporaries in the field, her career never blew up like some of the other models. She did a few conventions (where I met her in RL), but never got the gaming contracts or promo gigs like the more popular models.
She seems cool and has a decent personality, but if cosplay isn't her thing anymore and her lack of updates seem apparent, then I guess its time for her to move on from this part of her life.
I talked to her a while back on her OF and she mentioned she was more interested getting into product design and creation, not necessarily cosplay shots anymore.
Also the most she ever showed was her tits, never did full pussy or solo/toy vids. Being that she has a kid and will probably want more in the future, her making that kind of content is out of the cards for her.
So if she was to move on I'd wish her nothing but the best.
