If you have your family's blessings, and she has her family's blessings, then you can commence with communicating with her, within the shar'i boundaries of course. That would be something positive, to get the know the person prior to the marriage ceremony.
However, if it is away from parents knowing, and without any correct guidance, then you should not do that. A male/female going behind their parents' and secretly communicating with another person, wanting to supposedly marry them, is not at all advisable.
Parents should never be the last to know. That is a very disloyal trait, and in most cases ends very bad. First step is to have family involved, and then everything will fall in place, in shaa Allah.
With prayers for your success.
