Not sure if I can deal

Soo what does one do or how does one feel when your significant other is addicting to watching corn? It's not soo much just the corn but the accounts and subscriptions and hiding things it feels like cheating though I guess some may not classify it that. I just dont know what to do or how to feel. We've talked about it. He said he would stop. Hes been getting what he wants more often if you know what I mean. Thought that would help but turns out not so much! Im just looking for some advice maybe support or I just dont even know. How do you even talk about this with someone close to you. Ughhhh
