Aside from how you feel about her it is important that you (naturally agree) on the major things as well as have the same goals for the relationship. The dating/courtship phase is more than going out to dinner, movies, concerts, traveling, and other events. This is a time for doing "due diligence" to determine if this is someone you want to have an exclusive relationship with or possibly spend the rest of your life with.
A lot of people make the mistake of becoming "emotionally invested" during the infatuation phase of a relationship before they actually get to know the "authentic" person. At the start of a new relationship most people bend over backwards to "impress" those they are attracted to. This may lead one to belive they have found their "soul mate". A couple of years later when this person reverts back to their "natural self" you might feel that you were a victim of "bait & switch".
It takes more time to get to know someone than a lot of people are willing to invest these days. It's not uncommon to hear a person say, "He or She is not the same person I fell in love with." I wrote about this awhile back. " Relationships: Do We Save Our Best for the Beginning?"
One other important requirment is, in order for her to be "the one" she must also see you as being "the one". - Best of luck!
