AIO. My bf is getting bothered that my friend gets me flowers

My friend(F19 gives me flowers every week or two. Today I(F18) told my boyfriend(M20) they looked nice next to the ones he gave me. He got upset and said what I included. It’s not like this is a surprise to him. It’s been going on since we started dating. I thought it was harmless, but now I feel irritated by his messages. Am I overreacting for being bothered?
