Concerned about baby 😪

My Husband has been working crazy hours lately so we only really see each other on the weekends. I tend to 4 children on my own all week. It seems like every weekend all we do is fight. We're either bickering, or full on yelling at each other. He's convinced it's my fault, I'm convinced it's his (I'm sure we all know how that goes). Sit down talks don't seem to help at all and only escalate things more. There are days I wish I could just leave, for the health of my baby and for the sake of our children that keep having to hear it. I know this just may be a season of our lives right now that hopefully passes, but I hate my marriage right now. Today he told me all I do is sit on the couch all week while he busts his ass. He said he would love to trade and have my job. Although I'm pregnant, I'm a clean freak, my house is immaculate, there's always hot meals made, laundry done. You would never know we had kids besides the obvious things like toys. So, I'm not one of those women who don't clean or cook. I also try to find time to put myself together every day so that I don't look how I feel. My kids are always clean and well-kept as well. I'm telling you this only to paint a picture of what my days look like in comparison to what he's saying they are. Counseling seems impossible right now due to schedules. Idk, just needed to vent.
