@Caseyj,
She wants to meet with you from what you have written but as Punkey stated she already had plans but doesn't know the exact times days etc until the girls tell her.
She said "Wow" and that I think is what bothered you, wow as in can't wait or wow as in already? But, she also followed through with "off course" let her text you if she doesn't by the weekend, text her with a comment about how did the farewell go with your friends, I burnt the dish waiting for you, just kidding so when are you free young lady.
Something along those lines, casual, fun, and thoughtful.
