My 1 month was yesterday and everything triggered me. I was a weepy mess - even cried at Modern Family.
You are going to feel sad and alone whether he is in the room or not. Strangely WH has been great about holding me when I cry except for last night of all nights. I know he was tired but the occasional pat on the back while I wept kind of made it worse. I didn't say anything about the date, maybe I should have.
I don't think having him sleep on the couch will set R back, but maybe giving him the chance to be there for you will move it forward.
