No i don't think she did. Her visions are based on peoples desicions and change all the time. Jasper didn't go to the party and think 'oh i think i'll bite Bella tonight'. I was a quick decision after he saw the papercut.
I think she knew and hid it out of embarrassment または even pride. She probably thought she could stop him. If not, there always has tobe a reason for Edward to leave, otherwise how would we have gotten to know Jacob?
