This issue clearly is very important to you (and I would agree with your stance on it!)
The idea of making a plan for the worst case is a very good one. I would consider two scenarios - if H comes to you and says, I've changed my mind, I do want to do this - and if H does it behind your back. Your response might need to be different in each case.
I would just make sure that H understands that you are not trying to "control" him, but are trying to do the best thing for him, you, and the R.
Do you think the friends are pressuring him? If so, what do you think you or he should be doing about it?
Good luck!!
