Maybe it’s me?

So, when my boyfriend says he has to tell me some or ask me a question. Sometimes he says I’ll tell you later. So when ask him “what is it that you have to tell or ask me.” He says never mind it’s not important anymore most of the time. Then sometimes he doesn’t tell me and sometimes he does. To me because that’s really annoying. Because would like to know what you have to ask or tell me. Then, a couple of days ago. He said that he has to tell me something text me when you get a chance. So when I did text him. He said “don’t worry about it, it’s not important.” I got really irritated.. maybe I’m just being dramatic and I’m taking it overboard... But I was like “omg really with the *rolling eyes emoji*. Then he told me everytime I have to tell you something or ask you something I always blow it out of proportion and he doesn’t want to bring it up and it’s getting irritating. I didn’t want to start an argument or anything over text so I said “okay.” But I would rather talk to him over the phone about it. Maybe it’s me? I will talk to him about it. I just talks input on it too
