Can somebody prioritize the relationship they are in more than the person they are with?

Well my boyfriend started an argument out of the blue and blurted out that all I do is complain. I didn't have the energy or mental health to even argue back so I just let him talk. He did say some hurtful things but the one that stuck to me the most was the fact that he said all I do is complain when I'm just simply vocal about what bothers me. I do take time to listen to what he has to say and I do wonder where all that came from. But unfortunately all that he said stuck to me and I vowed to never complain again. So lately he's been doing things that I don't like and it has been draining. After a long time he finally realized I've been off. He asked me what's wrong and I just said I'm not okay. Now I'm trying to not complain because I have built up issues in me about the relationship but if I were to say something it'll be considered complaining. I'm kind of hoping for him to ask about how I am in general but not about the relationship. I haven't been okay for a long time. I decided to tell him that despite the relationship, I haven't been okay. But when I try to talk about how I am, he always brings up the relationship when all i need is to just to be heard for once. It's like even though me and him are together, he cares more about the relationship more than me as a person. I don't know if I'm making any sense. I don't know what to do...
