Unfortunately a lot of parents hope that their children will turn out EXACTLY like them. When they see that the child has their own life and their own priorities that are very different from their own it is a diffulcult thing for them to accept.
I think in this situation it is only a "time will tell" thing. In time your parents will see just how importent he is to you and also how wonderful he is. This is not something that is going to happen instantly.
I wish both of you the best and I know that things will work out like they are supposed to in the end. They always do!
