Boyfriend and his friends

I have been dating my bf for over a month now. We've know each other almost 2 months. After about a month of knowing each other, he told me he loves me. I have never been happier. Over the next few weeks, he tells me that daily. But last week, he went on a trip to LA with his guy friends. I am so happy that he's getting to have this great trip, but I never hear from him. I'll occasionally message him and 95% of the time, he doesn't respond even though he's all over social media. When I finally get an answer, he tells me that he's extremely busy. He tells me he misses me, but my paranoia can't help but question that. Also, he doesn't say that he loves me like he used to. I know I might be overanalyzing things, but I wanted to see what y'all think. I know I'm probably going to get someone's opinion that'll break my heart, but I still want an outsider's take ok the situation. After so many days and weeks of telling me how deeply he loves me, could something have changed so quickly. He tells me he misses me and that he thinks about me all the time. Could he be lying? Help, please!
