Sleeping on couch with 17 month old

My son hasn’t been feeling well and has been sleeping with me for a couple of nights and to start off every time he cries or moves around my boyfriend throws a fit and starts calling names. Called him a dipshit. So that pissed me off. Meanwhile I’m 16 weeks pregnant and severely constipated and having awful stomach pains. Then he puts a pillow between him and my son because he can’t be touched by him. So I’m hanging off of the bed and my son can’t move so he’s not sleeping. I’m in and out of the bathroom in pain. And then I tell him I’m hanging off the bed and he flips out. I grab my son and now we’re on the couch. He’s saying awful things about me while I’m leaving the room. Ha has a way of pinning things on me and making me feel like I’m crazy or did something wrong. Tell me I’m not in the wrong for this...
