I made it through my first year and 9000 miles before my first crash but I made plenty of mistakes before then, and in my book a crash is just a mistake that hurts a lot more! Analyzing your mistakes is where you really learn so that hopefully you don’t do it again. Some are easy to understand, like inattentiveness, some are more subtle and require some thought and maybe advice from more experienced riders. You and I will be learning (and making mistakes) for a long time to come but hopefully the crashes are at an end 
+1 on Owlie’s comments on the hubby thing. If riding with your hubby makes you ride outside your comfort zone then it’s better if you delay that excursion. But 30 miles sounds like a nice distance. It will be over in a flash and you will be wanting more.
