Going away tomorrow (actual 2nd anniversary tomorrow too). We live together. Pretty certain I'm going to get 'the talk'.
He has been distant ish since Christmas but the past few days have been really weird. Culminating in a massive argument last night (he went to bed before me because my DD was playing up and when I went to get in our bed he had strewn a big pile of clean laundry across my side. I said that seemed very passive aggressive and he shouted at me and slept on the sofa. I've sent him a link about complex trauma today to explain why I can be a bit odd in relationships (sexually abused since 5, was raped when I was 11 and was in a very violent marriage) and he basically replied with thanks for the info but I still don't know how I should have responded to the passive aggressive comment 
.
Tonight he is barely looking me in the eye and keeps going into our bedroom and is on his phone (gut feeling to his ex, probably moaning about me).
I don't know what to do.
