Should I break things off?

I’ve been with my boyfriend for 2 years and I feel like every time i’m sad he isn’t there for me. This week has been really hard I’ve had a family issue and one of our friends just passed away, I feel like I have no one to talk about my feelings. He is always busy with something and I have already told him I really want to talk to him. I’m just over it. What do you think I should do? Mind you when he’s upset or sad, I will drop everything to give him a phone call, I answer his texts right away. I’m just tired. I really love him though..
