XBOX OBSESSED PARTNER

I have dealt with my partners Xbox obsessive for a very long time but lately it has gotten so much worse, what makes it the hardest is he doesn’t see a problem with it, can’t help someone who doesn’t see it’s bad . We have two kids, he is constantly on the game. It takes 12 hours to hang some washing out, or wash a few dishes, I’m lucky if he does both things in a day. It gets to the point where he skips work for the game, meaning all our visitors (mainly my friends&fams) come to visit and have to put up with hearing him talk to his Xbox live friends and 100% of the time is foul language and yelling, me and our kids have to listen to this everyday and literally early hours of the morning and it’s not fair, but he doesn’t see anything wrong with it and ignores me when I speak my mind! I seriously want to end our relationship because of this issue because it isn’t how I pictured bringing up our kids!! No matter how I approach it or how many times I bring it up he ignores me or will get off it for 30 mins max and straight back on. He does NOT ACT like my partner or our kids dad and I can’t stand it anymore.
