OP, and everyone else:
How would you feel if this were your 16 year old daughter and a 28 year old man?
I know my answer won't be the popular one but I would react the same way. I would want to be in the loop about what is going on but I would not prevent them from seeing each other even if it were a romantic relationship. I would want to meet them but having been in that exact situation myself as well as having bad experiences prior to the one that worked out I consider myself a good judge of character and know the warning signs to look for. And I don't consider age a warning sign in and of itself.
what you were trying to express. This was not a "brilliant insight" on my part; I'm a devout, conservative Christian and I have a similar understanding of God's order of things albeit applied much less dogmatically than Gothard. 

I'm just now recovering from the one about mission trips to England!
