Am i in the wrong or him

Me and my partner have 3 living children and 1 angel baby. We are currently pregnant with our rainbow. Ive been so anxious this time around and whenever i try talk to him about my feelings he just replies with stupid comments making me feel like im being selfish for feeling how i do. Since being pregnant i just feel we have drifted apart he seems to not be bothered or supportive. Today he has gone out and messaged me some nasty things saying he wants us over because im "a boring mardy bitch" all because ive asked him to go shop for me. Im moving house and he expects me to watch our children keep on top of housework cook/clean as well as pack all by myself. I constantly ask him to go on day trips but he always replies that he cannot be bothered only time we go out is if its to the pub because thats all he ever wants to do. I feel like hes just causing reason to leave ive felt for a while hes cheating (no evidence just gut feeling) who is in the wrong here.
