Hi sublimenirvana, welcome to A2K!
You only really need to make decisions about colleges after you've gotten acceptance letters, right? You can go ahead and apply to however many you want. When do you get your accepance letters? (Sorry, I've forgotten the timeline on this stuff... almost 15 years removed from it, myself.)
If you don't have to make this decision anytime soon, just don't. See how things go.
If you DO have to make this decision soon, well, definitely talk to your gf about it. I'm assuming there is a word missing in this sentence:

Is the word "know", as in "I don't know if she wants to go to the same college"? If that's the case, definitely, definitely ask before making any decisions.
