Everyone complains about their job (except me!!! LOL!!!!Yeah right...). Just listen, ask questions, show some empathy and let her vent. This is a great opportunity to work on listening/empathy skills).
Try not to take it too personally if your W has sleep problems. My H has them too and sometimes he'll put a sleeping bag on the floor or go down to the office to sleep. When he was "separated" from me just before the D, I even put an extra bed in our bedroom. She definitely should not be sleeping in your son's room. That's not healthy for your son. But a futon or "guest bed" in the office would be best (and, of course, appropriate for the separation).
There is no arriving, ever. It is all a continual becoming.
