She probably does right now, but someday she will wish she had back her M. She doesn't realize what is really important in life b/c she is messed up.
I can see how you read all her signs as her wanting the R back, I would have done the same thing. Just goes to show you that it takes lots of time for them to completely come out of their fog and out of their MLC.
She will realize how lucky she was to have had a guy who was willing to do anything for her, change himself too. By that time it may be too late b/c you will have moved on with someone else who appreciates all your wonderful changes.
