Fighting with husband

I am constantly depressed because I'm unhappy in my marriage, I am 20 weeks pregnant and we argue and fight a lot and I always cry, he always interrupts me, and talks over me which leads me to scream over him etc etc. what affect will this have on my baby? I always try to calm myself down and rub my belly or walk away but I'm still stressed and crying by myself. I am trying so hard to keep it together for the baby, I just can't always control the situation. Will my baby be okay?
