Yeah I heard that too. People were use to just him and the GF fucked shit up. I think that is when a lot of the lies got exposed, because a lot of times he would say he was demi-sexual or somewhat sexually attracted to guys and then she would be like he has not attraction to guys at all. She even said at one point he hated doing CB completely and was just using everyone for money. This is just stuff I heard, so can't say for sure, but word to the wise: enjoy watching his show, but avoid giving money.
Find it a little harsh to say that if it's just rumor lol, maybe someone is really angry but all I can say is that in apperence he seemed like a nice person, an emotional guy, it's always possible that he faked it all but it's a fact that he stayed hours online talking about almost anything, just making jokes and conversations without asking for tokens and if someone was asking for something with tokens he always did it. He also did complete shows without setting goals (although he received tokens because he had built quite a solid community) and even end them with shower shows without asking for more. So in public it seemed totally fair, more than most

.
For the part that bringing his girlfriend maybe have made people lost interest on him, if it's part of the reason he left, it's sad, I don't understand those who absolutely want the model they watch to be gay. He love girls, fair enough, they were very cute together so let's enjoy what he could give !
And if he questionned his bisexuality, I don't remember him saying that serriously, it's the kind of things said after hours of conversation with a tchat that deseperately want to turn the model gay and ask the same questions over and over again, that and maybe the alcool too because for what I remember his shows were pretty much drinking parties

! Anyway we most likely never know for sure why he left, maybe it is some sort of backlash like you said, but from what I remember he was one of the most enjoyable model on the plateform so I keep that in mind
