Your life is going to change a lot every year for the next three or four years, where as his is going to become more and more stable. Things might be great now, but what changes are coming with you becoming a high school senior? Or a college freshman? Or entering the workforce? Or you getting your own place? All things to think about. Don't do anything that your pastor would disapprove of (assume you had one if you don't) and take it a day at a time. Either it will all work out when both your lives are stable, or you'll have moved on to someone and something different when your life is set.
