Teens just are not ready for serious long term monogamy, period. You should be spending more time with other guys. It's how you learn about differences in people, and how you decide what you like, and keeping it more casual is better for the huge number of changes you go through at that age. And you need to work on that jealousy, which is a poison that can ruin relationships all throughout your adult life.
