since you have projected to her that you are uncertain about the relationship...she will reflect that and ask you these probing types of questions. the key is to not be fazed by them at all. you want to go at your own pace. when she says something like "I'm guessing I won't see you for a while after tonight" you don't want to respond with something serious. you wan't to take it light-heartedly and respond with something fun and casual.
