I mean we at least know she likes the attention she is getting and all the followers/subs she is gaining. Beyond that who the hell knows? We don't know how she feels. But she is very upfront that she is an egirl who badly wants to climb the social media ladder by any means necessary. And he is the biggest prize on Twitch for an egirl to bag.
But even if she is using him, he is also using her for content on all his platforms. So he is also getting something out of it. Hell, the last girl he dated has 3 of his cars worth 500k and didn't pay rent for 7 years, and ate a ton of food. If this girl just walks away with a little of his money and some followers, he came out ahead.
