Need to let this out

So me and my boyfriend have been dating for almost 6 months now. we have had a few arguments before but it is generally over the same topic (Us not talking as much as we used to). He went on vacation for a little over a week and wasn't really able to talk to me. It didn't affect me that much because I knew that he was busy and he wouldn't have time to talk to me. He got back a few days ago but he still isn't really talking to me. I feel like he's getting annoyed with me. My phone shuts off at a certain time and I can't see what he texts me after that time. Right now I have 12 message notifications because we sorta ended the night off with an argument and he didn't say goodnight to me until I couldn't see what he said. My anxiety is through the roof and I'm so scared he's gonna leave me.
