Games are stupid. Trying to make her jealous to come at you again would net you the same results as soon as she had you: she'd run and turn the other way again. You are better than that, if you want something serious with a girl, her kind of behavior is unacceptable. And she would not "change" if she fell in love with you. If she did.
She's so worried about ruining the friendship? She already did with her shenanigans. I say cut her loose. Feel free to let her come and go as she pleases when she needs something but I wouldn't reciprocate the behavior. I damn sure wouldn't let her try and kiss me and cuddle with me again.
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
