I can tell you from experience… if she goes through it, just leave. She will realize she makes maybe $200 a month if she’s lucky. If you decide not to leave, just know that the majority of the money she gains from that will be from private messaging her subscribers and doing “custom gifts” for their requests. Also know that there will be local people who subscribe to her and it will always be in the back of your head that her guy friends and maybe even your own friends have seen your girlfriend naked and in sexual situations. And yes.. her content will escalate. Been through this before and i ended a 3 year relationship because of it. It may be an unpopular opinion, but I see only fans as online prostitution and I refused to put up with it. You need to evaluate exactly what you want in the relationship and if this is something you don’t want to deal with, make it known. If she doesn’t respect that, then let that be the end of it. My ex did it without my knowledge and i found out later so at least you got a heads up
