I feel like my friend is starting to dislike me. I dont know why.

Me and my friend of 4 or 5 years used to be very close, hung out a lot not just in school, we even wanted to start a band a few years back. Then, recently (for a few months) he started acting different. He was often texting me or calling me first. HIM asking ME to hang out. And I dont remember rejecting him once. I also was inviting him outside, and he always went. Then later it started to die down. I was now the one who asked him, he always said "idk". He rarely went now, but still sometimes. But its developed now into him not just not texting but not even responding to mine. And I mean sure hes busy i get it. But no, I just found out few days ago he doesnt want to hang out with ME specifically. Let me explain. on friday I asked him to go to the mall to get some food. He said he wasnt busy so maybe if he feels like. The next day, nothing. No text, call no response about if he wants to or not. I said to myself "I guess he has to like clean his room or something" but he couldve texted me that hes not going. But then I recieved a snap that hes with another friend. (He asked my friend after friday) so he basically ghosted me for someone else. When I asked him about this, he said in angry tone that he also had other friends. I dont get why he didnt say this to his other friend when he asked him to hang out. So tell me am I reaching or does he not like me anymore?
