Is this girl right for me?

Ok one day I was minding my own business when I got this random text message, its was this one girl who mistakenly got my number, well its been like a week since we met and we have been talking non stop.When I hear her voice I get this weird feeling, its kinda strange. She is two years younger than me (just turned 14 and just turned 16). What should I do? Is she right me?
