Irritated

I need to vent (kinda long) My husband and I have 2 kids together a 6 year old girl and a 1 year old boy for about the past 4-5 months we've been fighting ALOT ! he's always playing video games and not helping me with our kids btw he does not have a job and I do everything he helps with diapers here and there but I do EVERYTHING ELSE I've ask him to help me more with the kids because he can be stuck on video games ALL DAY and he starts a fight I'm so tried, irritated and it's driving me crazy, more that the kids are always fighting and crying and I get no help plus cleaning and cooking I've tried talking to him but nothing seems to change plus he has his family staying with us and yeah they help with the bills but they don't seem to help with cleaning or cooking what's so ever ! what should I do ? Any advice will help
