Am i overthinking?

For some context, me and my boyfriend always say the cliche “i love you” - “i love you more” to each other all the time.. i will admit that i am young (about to be 19 in April) but when i love someone, i love them a-lot, and i know that i love him more but this hurt my feelings, i guess i just want to know if I’m overreacting… because this has not left my mind… i honestly dont know how to feel. ( please dont hate, i just need to know if i should be worried about this, i know he’s a really good guy I’m not saying he isn’t. This just caught me off guard)
