If you truly believe he is "the one," then go to him and put all of your feelings out there. Who cares about the potential for rejection? Don't let someone you are in love with get away because of a stupid misunderstanding.
I do have concerns about your boyfriend's jealousy over your friendship, particularly his inability to discuss it with you before ending the relationship. Was his fear of rejection stronger than his feelings for you? He could have at least described his concerns before breaking up with you. Be wary of any requests to end your association with your best friend. Maybe you need to modify some behaviors and your boyfriend needs to adjust his comfort level and acceptance of the friendship, but it would not be appropriate to require a partner to end a friendship -- even if you believe your boyfriend is "the one."
