ForGump, I would tend to agree with Jruss in that you should move back to the marital bed. If she wants to sleep separate from you then she should move to the couch. I would strongly be against you separating physically as once this happens it is more difficult if there is any chance of reconciliation.
I remember having an R talk with H (mostly me talking him saying nothing) asking him if he needed more time and he said yes. A month later I said he should leave if he really wanted to and he did. I wish I hadn't said that, I wish I had givien him more time. He may have left anyway but I will never know.... I know it's hard living with someone who says they do not want to be with you, I lived it for 6 months but I can say now that it is a thousand times better than being physically separated because the frustration and pain of not being able to see them or speak with them every day worse. Take advantage of your situation and really show her that you can be the husband she needs and you want to be...
