AIO I (27F) want to end things with my bf (27M) because he doesn’t make me happy

My boyfriend and I have been together for a year this summer but I just feel like the relationship isn’t what it use to feel like.

For reference I now live with him, I’m very close with family, we practically do everything together. I work from home, he works during the day as well so we’re not always up under each other but outside of work it’s always just us. I feel like our “crave” for each other is dying out. I don’t want to have sex with him, I get annoyed when he tries to initiate it, I’m not as into him as I once was. I can’t see myself without him but in this moment I don’t want to be with him.

What advice do you have for those who’s love is dying out?
