I want to start a couples channel

Me and my boyfriend have been together 8 years and I've always wanted to start a couples YouTube channel. I've been trying to talk to him about it starting one but he said no. He's a very private person and doesn't want his life out there on the internet but one thing he brought up doesn't make sense to me. He talked about how 80% of couple on YouTube break up, 20% don't and only about 5% are probably together because they still love each other and the other 15% is still together because they know their careers wouldn't survive without each other. I feel like he's calling our relationship weak because you have to have a weak relationship if YouTube is able to break it up. He thinks couples get too caught up in YouTube and money and forget about each other. Sure maybe that's true but that's because their relationship is weak. He's pretty much calling our relationship weak. I really want to be a couples channel and if he doesn't it's partly telling me he thinks our relationship is weak
