She doesn't want a relationship. And she doesn't want a relationship with you. Sorry. When she was asked if she likes you, she did not say yes. That is an important point to consider.
If you don't want to be just buddies with her, you have to leave her alone. She has set up the groundrules and it is up to you whether you want to follow them or not. But not following them means not having her in your life either way.
The best you could probably do is to remain friendly with her and tell her that you like her and think that the two of you could have fun. If and when she felt comfortable with that. Then don't bring it up again until she does. But don't stop living your life waiting for her. Go out with other girls. Be active. Have fun. She may never come around and that is something you have to deal with.
Good luck.
