Just to clarify, we are still in house together, major building works going on so house is a mess, bedrooms all over the place. It has made the situation even harder. W swans in and out as her mood takes her. This is my predicament. I think given what you said AStander, I did the right thing. I did exactly as you suggested above.
Some great advice and encouragement from everyone here. It is appreciated very much.
Good, yes I agree it sounds like you did just fine. Separation seems terrible and scary, but a lot of times it really helps with these situations because you can establish rules and boundaries that you can't have while living together. It also gives the WAS the time and space they want so badly.
