I think I'm hopeless. What does she think?

You know what you want so let it known and tells these girls what's up? And then move forward and get with the girl that your into.

Dude, it doesn't sound like you know quite what you want. And both of these girls deserve more than what it seems like you're willing to give them. Take a couple of steps back and give this whole situation at least a couple of months. I promise it'll look totally different by then.

Don't make a rash decision. It'll only end up making you look like a jerk, hurting one or both of these girls, and will likely give you some ripe candidates for regret later on. Wait for the girl who trusts, honors, and respects you enough to stick with you and be in a committed relationship. Also, since you're 16, wait until you're mature enough (no offense) to lead a woman in that caliber of relationship. Anything before then will only waste your time and wear on your heart.

And don't screw girls over, either intentionally or unintentionally. There are enough guys who are good at that. We don't need any more.
