She was agreesive/jealousy because *you* were interested in somebody else instead of *her*. You should have followed it up with is she available to make sure she knew that you weren't just making little wussy comments. I would wait till next weekend if you're at all interested still, and I imagain you are. Don't call her ahead of time though, call her and say that you're about to go *insert something here* and were calling to see if she wants to tag along.
