You might be better off taking the rest of the season off. With a fractured leg, you don't decide when you're ready; it tells you. You went back after six weeks, tried to suppress the considerable pain you felt (that's a signal from your body that it's not right), then reinjured your leg. Why risk repeating that cycle?
Yes, listen to JoeR. Just wait till next season, and come back stronger. I was advised not to run for 4 months after a meniscus tear surgery, and I tried running after a month. Let's just say it didn't go well. Sometimes we get carried away by the excitement and thrill of snowboarding, but it is important to remember that your long-term health > snowboarding.
We might even have a better winter than this year.
