Video game addiction ruining our marriage

I never thought I'd find myself believing in vidoe game addiction ... as an addict myself (former percocet) I assumed addictions stop at food sex and drugs. Over the last 8 years I've found that video games have just as much power over a person addicted to them as any substance. ..my husband and I just welcomed our 4th baby into the world (6th between us) . We had a darling little man. I had my first c section so recovery has been much different than I'm used to. . My marriage is in the shitter. Point blank I am essentially a single woman living with my husband. Our marriage is in tatters bc of his video game addiction. My husband plays for hours and hours a day, spends his night up all night playing call of duty. He has left me to care for our children, house and animals by myself so that he can focus on his game. We are no longer sleeping in the same bed because he stays up all night yelling into his headset and I cant sleep through that. He gave up his xbox for a big chunk of the pregnancy and our marriage was magical. His friends kept bugging him to log back on and he promised it was going to be a "here and there ' type hobby. Here and there has become his number one priority. ..I don't know how to fix this. I can't. I've talked to him. Cried to him. Shown him starictics. I mean we arent sleeping together right now and he knows the reason! Even that isnt enough to snap him back into reality. Our kids are young. 7 weeks , 1 year , 3 , 6 , 11, 12. I'm drowning trying to stretch myself so that each child gets the attention they deserve. I'm stressed to the max making sure everything is done in the house. . I'm lonely, heartbroken.. this has been 8 years of the x box coming before me , with small periods of him yanking his head out of his ass. Yet he always returns back and myself and the kids get pushed back into the pile that takes away from his game. . Idk what to do .. I'm lost. Help me ladies
