Boyfriend ignoring text :((

My boyfriend and I have been dating a year and these past couple days for the first time ever we’ve had to cut off communication with each other completely while he was away at military camp. Today, he came back and he sent me a good morning to which I responded with a good morning also. I thought he’d be really eager to talk to me as I was to talk to him since I missed him from not speaking to him for a few days. Well, I texted him over an hour ago to which I’m not surprised because he doesn’t usually respond back quickly anyway but I was looking through my insta dm’s only to see he had been on instagram after I had sent the text. He does that sometimes and I’m unbothered, but this time just really hurt because I was anticipating talking to him and thought he missed me and felt the same way. Any of y’all have any advice for me?
