I'm pretty slammed at work today, so I'll have to be brief.
Are you at a point with you that you can live with whatever happens - seems like you are as you told her you were ready for D. If so, why not sit down with her and tell her what's on your mind? Not in a pursuing way, but more in a I have done some soul searching, and here is what I have noticed about me...Let her know you are not perfect and that you would like to work on your M - that if she decides not to, that is her choice and you cannot stop her. But, you don't agree with that choice. I think you can do this in a way that is more clearing the air on something that may have been confusing.
I will defer to the more experienced on this one. But, I think if you couch your discussions in terms of leading you both to a new M, it could be helpful. Just no begging/pleading. Then shut up about any more R talks and start living your changes.
