Questions about a suprise for my girl...?

I broke up with my girlfriend bc I got tired of fightin everyday.. thing is, I miss her! BAD! but.. she says she's not gonna jump back into this so quick and get her heart broken its been 2 wks.. so tomorrow night.. I was gonna get a rose and a card and while she's out at the movies with her girls I was gonna secretly sneak up there and put it in the windsheild of her car.. The card I'm thinkin should read.. "Another Chance?" on it.. but IDK, should I put more? or what.. help!
