Silent Treatment...

I honestly am so irritated right now. My boyfriend won't talk to me. Yesterday we were supposed to have a nice dinner with my grandma but I said something that pissed him off so he didn't come. This dinner would've been the first time he spent quality time with my grandma. We've been together over a year now. I just pushed his buttons a bit because we lost the heart on snapchat. I asked to see his best friends list. I told him I was joking but he wouldn't have it. The last message he opened and didn't respond to was something along the lines of "Can you please just move past what I said for one day so that we can spend time with my family?" He hasn't answered me since. That was yesterday in the morning. He won't take my calls either.
