Is anyone else having marriage issues during pregnancy

I’m 32 weeks pregnant with my second child, my new husbands first. With the first child I had gone through a nasty separation with his dad and a nasty custody battle. Things are great now with visitation and my oldest child. However my current husband says that I coddle my son too much. My husband fussed at my son last night for hitting the dog because she bit his butt. I immediately went over and disciplined the puppy since we are about to have a new baby. He said I had to right to discipline the dog because she bit him for hitting her. The second senecio that happened last night. I let my son do my makeup he’s 5 and the make up stinks hence why I never wear it. So my husband comes over while I’m having a conversation with my son and interrupts and starts saying that my face stinks and omg it smells so bad I asked him multiple times to stop and go away while I was having a conversation with your stepson. He then goes into the kitchen and starts interrupting on purpose (we were just telling our 5 year old the other day you don’t interrupt people when they are talking and my husband just sits there and is being rude.) So the 5 year old play fightingly hits my husband a couple of times and tells him to stop. I continue the conversation with my son and then informed him that no matter what we don’t hit. My husband is absolutely pissed off at me for not disciplining the child and coddling him. So for an hour after I got the 5 year old to sleep my husband fusses and yells at me because I show him no love and I coddle the boy and that he’s sick and tired of thinking I don’t love him. He also told me that I needed to hurry up and have this baby so that we can see if our marriage will workout. Did I do something wrong here? He fussed at me so bad I cried in bed for an hour before having to get up and be up all night with our son. I am falling into a deeper depression because I don’t know what I’m doing wrong. We have been arguing on and off for months now.
