am i really cheating on him?

so I’m 17 and have been with my boyfriend for 4 years now. we’re in college atm, i was waiting for my boyfriend when I saw my friend who is also a boy, I have been his friend for around 2 years now; he told me he would keep me company until my boyfriend arrived. We were having a general conversation and I said I was hungry so my friend brought be some food and then my boyfriend turned up and now thinks because he brought be food that I’m cheating on him. Like genuinely nothing happened apart from my friend buying me food... is that really cheating???
