I think my husband is addicted to Xbox.

So I genuinely think my husband is addicted at this point. He has always liked playing here and there, which I never minded. But over the last few months it has literally started taking control of his life. His daily routine is he gets up,goes to work, comes home and plays Xbox the rest of the day. Won’t even eat dinner with me like he used to he just gets his dinner and eats while he plays until 2 AM then goes to sleep. On the weekends when he is off all he does is play Xbox I literally can’t get him off of it. He doesn’t take care of the yard like he used to, I now mow and weed-eat the grass. He doesn’t do anything besides sit on that game when he is home. He spends so much money on unnecessary things for his Xbox and his games. He has never been like this before. What can I do? He doesn’t even want to have sex barely anymore. He has always been a great to me, this is the first real struggle we have came to in our marriage.. (been together for 5 years) So leaving him isn’t an option but I don’t want this to continue. He has his state test coming up and when he passes he will get a huge raise that we could definitely use. And he hasn’t even studied... it’s coming up not even in a month and the test is huge 😕 It’s like he just doesn’t care about anything anymore
