Just take some time out to relax and get yourself together, nothing good will come of doing anything in anger or without thinking things through.
At the moment all I can suggest is to back off. Let H have his space for now. If he's questioning the whole M thing then the worst thing you can do is keep bringing it up and wanting to talk about the R and M.
And remember, only some of this is your fault. an R takes 2 to make it work. Just the fact that you are here says that you care enough to want to make it work again.
Don't be angry at volunteering, it's a great thing that can give you both much satisfaction, but as with anything it has to be balanced.
