Issues with the Boyfriend.

So tonight someone snapchatted me a picture of my boyfriend at McDonald's and said spotted. So I texted him and said "you come to town a lot." But I meant it in a bugging way cause he always complains that he's stuck at home since he doesn't currently have his truck. Anyways, when I said it, he got all angry saying that my friends and I are annoying and saying that he can't do anything without me asking. Yet, he does the same thing. As soon as he sees me out, he instantly asks me what I'm doing. Yet, claims he doesn't. And his friends also text him when they see me yet he claims they don't. I don't understand why he got so angry. When he was calm, I talked to him and he said he was mad cause he didn't get to tell me himself that he was at McDonald's. And that it's like the second he gets to town 10 people already told me what he's doing. I don't understand? I wasn't trying to fight at all.
