How do I get past just being a "friend"?

I think you need to make up your mind that you are going to take the plunge and just ask her out, but you need to be prepared to face rejection. If you don't take a leap of faith and just do it, you will never know. You could go on for several more years not knowing. At least if you make a serious decision and just do it, you will stop the cycle of asking yourself the question of whether she really likes you as more than a friend or not. When you ask her out, be truly serious about it. Buy her a bouquet of flowers and look her in the eyes when you speak to her. Let her know with your words and your actions together that you want a serious relationship with her. But, like I said, be prepared for rejection just in case, since you are putting yourself on the line. Either way, you need to find out.

It's true, you do need to realize if you really want to be with this girl. If she truly doesn't like you, that can't really be undone. My advice is to have more options open than just one girl. You will meet another girl you like (I like 100 right now). If she matters that much, play a little hard to get, hard to reach also. Don't always make time for her. This won't make her jealous, just regret her decision. Just make sure if you really want to go through all the trouble to be with this girl, because that is what will happen.
