Should I stay with my boyfriend?

I already know a lot of people might think that if I have to ask this, the answer is no. But I still would like advice.

My boyfriend is really idolizing the man Bryan Johnson, the man who wants to live forever. I’ve read about him, watched his videos, and read articles about him.

I’m not a psychologist or anyone professional in any way, but to me I feel like he has a glorified ED and his work is based off of his mental illness. I’m open to any criticism if I am wrong, because I’d like to learn.

Though from what I’ve seen, I don’t want this man’s teaching around my kids (hypothetically, if me and my bf had kids later on). I don’t want my boyfriend, who acts like he’s this guys boyfriend instead, around my kids either.

I don’t think Bryan Johnson is necessarily a bad man, as I mentioned I think he’s mentally ill. I feel bad for him, even if he enjoys his life. Although he isn’t directly hurting anyone I feel like he indirectly affects (some) people negatively. I think he believes he’s doing good, I just don’t agree that he is.

Im usually not a controlling person. I don’t care about political views, race, gender, or anything. Is this me being controlling and I don’t notice it? Should I stay with him? I don’t want my boyfriend with someone toxic either, zand if I’m the issue, I’d want to remove myself.
