Well, no one here can advise you perfectly. We/they can only make suggestions and give life examples. But, they may not pertain to you exactly.

So, without knowing a whole lot about the two of you, I can offer this:

(1) You are young. I suspect, being hasty, perhaps, that you might be more interested in the "thrill" of a sexual contact than just remaining friends. Having said that, I'll back it up with some wisdom (that the elder around here can most assuredly attest to)...that first year or two with your love is exciting but it will fade and the both of you will need to have friendship as your "anchor". Being married (or with) your best friend is about as good as it gets. Just ask anyone who has been with a girl for a long time (married or not). WHEN you can say, my girlfriend/wife is my best friend, you will most likely be about as happy as you can be. So, considering she is already a good friend, I'd say "go for it". But, choose your words carefully...which leads to item #2.

(2) As I said before, I don't know you two. Not sure what is between you two more than just a friendship. If it were me, I'd say something like: "I've known you for a long time. You're my best friend. I'd never want to do anything to hurt that connection we have. But, I have other feelings, too, and rather than let them be neglected, I thought it was important to see if you had any additional feelings as well. You see, it's hard in this world to find people that you feel might be your soulmate and it's stupid to pass up a chance to see it "this" is the one because you are scared. So, there it is! You can always count on this...that I will be your best friend regardless of how you feel about me and my words...because I care about your happiness and friendship."

Well, it might not be the exact words you would say but it's an example. All in all, I've found truth is the best thing to pursue.

Let us know what you do and how it turns out.
