I can not relate to you as a mother, I am only still in my teens. But I can relate to you in a way. My brother has one year of school left, and my mother treats him as a son. Unlike our relationship. But I do know that if you love something or someone as much as a mother should a son, you will be able to let him live his own life. You want whats best for him right? You want him to be happy too right? It most likely will be hard to watch him go, but he will always be with you, love has a way with bonding people, keeping them together.
Be strong.
