how to follow up with this girl I like?

Basically I follow this streamer and donate to her a lot. Basically most of my money because I don't really have to pay bills (living with gma) . I have a good position at Walmart but I donated enough to this streamer that I got to meet up with her and have sex with her (technically the money isn't for sex it's a legal thing) but since we met up at rhe hotel I got her number because we had to meet up and now I'm wanting to talk to her not during stream. I sent a text saying what's up yesterday but no response. She talks to me on stream still though. Idk I feel kind of like a dick if I bring it up but wth why didn't she answer? I give her most of my money. Just want to talk to her about work and how I'm trying to be more social at work and how ive grown since i started giving people compliments. She's really cool. Can't name her cuz last time I brought up her website mods got mad but how can I break the ice with her? She has a boyfriend but I just want to talk w her idc if she doesn't date or marry me. What do you guys think?
