She likes you. Whether it is as a friend or as something more than a friend only she knows. So how about asking her? If she says only as a friend then you are in the same position you are in now, if she says as more than a friend then maybe you can start a relationship, if that is what you are looking for. But, start with asking her.
This is what you don't want to do. ^^^ You are putting her on a spotlight and putting too much pressure on her. Just try some kino and sexual escalation next time you see her and see how she reacts to it.
