Lost spark?

I know I’m young, 17 in fact and he’s 19. Call it “young love” if you will. I’ve been with my boyfriend for a year in August. We’ve never gone on dates, nor done new things. Just the same. I feel bored, and stressed about my senior year/graduating and moving out. I feel the spark is lost, and I have my doubts. I don’t see anyone but him in my future. I am not willing to give up on him. I’d rather have my heart broken than break his heart. Any advice on getting the spark back?
