Am I wrong for feeling this way?

I’m going on a work trip and I’ll be in another country for 15 days. I wanted to spend time with my boyfriend cause we’re gonna be apart for quite a long time ever since we started dating (FYI: I’m 21 and he’s 19) and for the past few days he barely texted me or wanted to hang out with me. I’m extremely upset and hurt cause I’m going to miss him very much but I think it’s obvious he’s not gonna miss me. I tried texting him asking if he wanted to meet up today before my flight and he said he was gonna be busy playing videogames with his friends and that he couldn’t miss it. I’m not sure what to do, I’m extremely hurt. Am i wrong for feeling like this?
