Boyfriend doesn’t seem to care anymore

I feel lost writing this because I never pictured myself in this situation..everything always seemed so good and smooth. Recently I feel like I don’t exist to him anymore. I guess it’s like he’s tired of me now. If this is what it’s come down to, and I’ve spoken to him about it many times..is this the end of our relationship? I don’t even know what to do anymore it’s like I’m always in the wrong and it’s draining me significantly.

And what I mean by it’s like I don’t exist is that anytime I have a problem, even just a small one, he’s like mad or disappointed in the fact that I’m bothering him with issues or if I’m just not feeling good.🙈
