Well, obviously i'm up at 3am after tossing and turning for ages. 
Went out of bedroom and to an adjacent room to get water. Crept out of the bedroom in the dark and turned the light on in the adjacent room to, ya know, see. 
Came back to bed and partner is pissing and moaning I woke him.
He came back after a long trip yesterday and I made a big welcome effort with cleaning, cooking, tea on tap, etc. Feels like he hasn't appreciated of it...just been called selfish and unthinking. 
Aibu to be fuming!?
