My 19 year old little brother left angry yesterday, Husband told me it time to let him grow up am I a horrible sister for allowing my brother to live?

My little brother who had just turned 19 and is in college. I was paying for his college tuition in Utah at BYU , I wanted him to be at a Christian stander environment. My little brother has been with an angry additue with me. He wanted to exchange school because he wants to do whatever he wants. At BYU there's rulers he must follow I tough it was the best choice for him since he will be safe. But that little boy hated that idea. That little boy pack his suitcase yelled at me YOUR NOT MY MOM ! and slam the door shut. I stood the next 45 min crying I tough that little boy how to talk how to talk his abcs and number I teach him how to ride a bike. My husband tells me that this was going to happen at some point that the fact is that I am his sister and not his mother I must let him fly and experience adult life himself if he refuses my help. I feel horrible for allowing him on his own.
