Treading water - time and patience

[NYCPeter]

W came home at 3:30 - I was in our bed asleep when she came home.
When she came to bed, I got up and went to go to sleep in the spare room. Still awake 3 hours later (D9 woke up at 6:00am).

I do not want a W who comes home at 3:30 (she finishes work 1:00-1:30). I don't want to wake up in an empty bed in the middle of the night and find my W is not there, wondering where she is. This is disrespectful to me and something we have discussed several times yet she chooses to ignore or decide she doesn't think it's important.

I won't say anything today, just go about as if nothing happened. If she asks about me getting out of bed - I'll say I had some work to catch up on.

This is becoming a real issue for me and I really don't want to talk to her about it anymore. She's aware of how it makes me feel - guess I need to decide if this is a real deal breaker for me and do something about it.
