Don't do it!There's some good bits and pieces of advice above this post.
You both need some time away from each other to evaluate the situation and determine how to go about your lives. Whether it be together or apart.
Tell her you've already made plans and maybe you guys can make some plans together later on once you both have some time to let everything sink in. This will make her think.
Go out and try your hardest to have a good time!
