Thanks for writing. If your rose's leaves look healthy, I'd guess your plant is putting its energy into getting established in your garden so it can perform well next year. If this is the case, it's actually a good thing it's not blooming more --- because that means it should do better next year than if it flowered more profusely this year.
I know it can be frustrating, but it's best to think of plants like this as a long-term investment --- put more patience in this year and you'll be rewarded next year.
