How do I balance my relationship and school?

So, I'm in a relationship and I love him dearly. We both love each other so much, and we constantly talk about our future together and other stuff. My problem is that I'm an honor student, and I feel like if I put all my time into my relationship, then my grades will slowly start to fall. Yet, if I don't put enough time in my relationship it might not work out. So how do I balance these things?? I love him, but I love school.
