Boyfriend Issues

So I'm a senior in high school. My boyfriend and I have the same classes, but we don't talk much because we're in class. Once it's lunch time, we get to really hangout, except he hangs out with his phone. I've gotten mad at him for this multiple times. All I want is attention, that's not too much to ask for. But whenever I bring up this argument, he gets upset because I'm upset. I don't think he has a reason to be upset, which only makes me more upset because it's like "fuck off you don't get it". Ugh I'm just extremely annoyed 😒
