Well, of course she likes you :)
Assuming you aren’t a troll since I’ve seen other posts and we’ve interacted before, some people can be in denial about whether their crush actually likes them. Don’t worry, she does! 🌺
I also wouldn’t bang someone or even be “down to have sex with” I wasn’t into, and I wouldn’t tell them we could date if they wanted to.
Friends with benefits exist, but she’s saying you guys can be if you don’t want to date her. Doesn’t really sound platonic to me. (I’ve also never had sex with anyone who wasn’t my current girlfriend, but still.)
