I think the written word can be read / interpreted in many different ways, and you can't always ask for clarification, however there were a few things Garnet had written in the original post that raised alarm bells for many of us, and she did state that she has been googling divorce, which makes me think that she knows things need to change.
Some of the responses may appear to be harsh, and may be influenced by personal experiences or just different communication styles, but I think the over-riding factor is that everyone is concerned for this lady and is trying to be helpful / supportive. None of us want her to be suffering and in pain. Whatever happens I just hope that she is OK.
