I really don't think so in this case. Yes, usually e.girls lie or at least omit when they have someone cuz that would make less money flow from donos on twitch from their followers, but idk if was 2 or 3 days ago on stream, people started to talk about relationships and she ended crying some tear drops cuz she ended saying that maybe she didn't yet found true love but she will be ok as long she have cats (i'm serious, she said that). I felt sorry for her, seems like she's trying to cope. Probably some bad past boyfriends experiences (sometimes she tells some stories).
But yeah...i always had the sensation she never bullshits about stuff like that, so if she says that currently she's very focus in her work and that is not trying to find anyone now, might be true. Although, i would say as an advice, that when fellas start to create some sort of platonic/parasocial relationship with these girls, they will only suffer, so better not, cuz let's be honest, these girls don't look to their followers/fans with those eyes, yet i actually feel that some have this subconscious belief that they are their boyfriends.
Yes. She said that will keep uploading reaction videos to patreon and photos to OF. Now...about cosplay, i'm not sure on that matter. Idk if she will do them for Patreon or OF. But in reality, by looking at the Patreon leaks on the internet, she never did anything major in terms of cosplay on Patreon, maybe 3 or 4 outfits. Most are reaction videos that are similar to those on youtube and of course the Notty Dungeon, although i would say you don't miss much, unless you're into gay porn, seeing women taking dildos horse size, goofy sex clips and sexual memes, cuz it's essentially that that they send her. Stuff that makes her feel quite disgusted, yet she react to them cuz are her patrons (her mods and more loyal followers from the large part) that send that content.
