Whale prefers my friend

I met this guy, he’s buying me whatever I want and whenever I want but I also try not to ask for too much as I made the impression that I’m not after his money. It didn’t bother me that he had so much girls he pays until…. He texted my friend, and turns out, he definitely finds her much hotter. That means, he pays her much much more. She gets like triple amount of what I get… And yeah, it’s just annoying when he starts ghosting me and then she tells me he texted her. I actually felt bad for him as he said he’s addicted, so I tried not to use him as much… but now I feel like I’m missing out on a lot. I already made the impression of „sweet and innocent girl” that doesn’t want to drain his wallet, so I don’t know if switching up won’t destroy the „bond” or whatever. What should I do? Should I slowly start switching up or just accept that I will get less? He never told me (obviously) he finds her more hot, but it’s pretty obvious. I noticed too late that he prefers dominating women instead of the innocent ones… Idk what to do.
