He 36M talks about something else when we talk about a problem in the relationship. I’m 25F

It happened multiple times that I would confront him or want to discuss want happened. And then my boyfriend it’s just like oh do you see that? or are you also cold? And that’s it. I find it very strange. Has any of you ever experienced something like this and know what it may stems from? Sometimes he just goes back to his YouTube video. I myself am avoiding conflict. But I know that talking can really clear up some issues.
