Yes SIN, I would have to say that she caught on to what your plans are per se. I would not say she is upset but it looks like the pressure to "make it work" may have tweaked her a little.
As far as OM goes you must forget him. He is a band aid and you must be the shiny gem of a guy. Let her see that she is making a mistake by letting you go.
All the other stuff will come with time but 1st you must look and most importantly feel that YOU are the man in her life. My W says our friendship saved our R and she is now wearing her wedding ring when we go out. It took some time but I was consistant with her. I personally think that they need that from us. The rest of her life could be a mess but you can be the rock for both of you and she must know that you can take her or leave her. "whatever" is a good motto for you now.

Order some men's health mags and ear the parts about healthy sex and let her see those. Things that make them go hmmmm??
