Well for what it's worth, here's what I think. A couple of things. One, you can't shield him from all hurt. Life happens, and if he gets hurt, he'll just have to deal with it. Two, he's probably better off having a somebody in his life than nobody. And three, it's probably better for that somebody to be like him rather than not like him. A non-aut might have a very hard time relating to him without pitying him, or trying to "fix" him, and either of those would be destructive and devastating. IMO.
