You are 100% right no one knows what is going on in his mind and I have come to the conclusion that they probably don't even know that is why they get so wishy washy.
Enjoy every moment this weekend and Monday night. Leave him with only good thoughts of you (ie. no nagging, pressure, yadda yadda) and how much fun you guys had together. The Corn Maze sounds like soo much fun, it was so hard for me to drag my H to those kinds of things...lol.
