How do I help my boyfriend make me cum?

We've been together for a little over a year. I had orgasms all the time when we first got together, mostly with the help of a vibrator though. It died 😣 I can cum without it, it just takes a bit more effort. He doesn't seem to want to put forth the effort and doesn't listen when I give him notes, even when I'm super specific. He gave up this morning, said I killed the mood. To me it feels like he wants me to cum only so he can feel good about himself, and not because it makes me feel good.
