Did she say you were the problem and blamed either all or the majority of the problems on you? Or did she assume the blame and apologize for her part equally?
If she blamed mostly you, chances are (I'm not saying definitely) that she's seeing another guy.
What type of "separation" is she talking about? If she wants a physical one, dividing accounts, etc. then she's usually wanting to conduct her business in secret.
