Feeling some type of way

This is probably a stupid childish post, but I'm sensitive and feeling some type of way. My boyfriend and I have been dating for almost 4 yrs. He likes to write music. anyways our first anniversary he wrote me a song and sang it to me. I brought it up today about it and he had no idea what I was talking about and it made me feel some type of way. I gave him the cold shoulder and told him how it made me feel and he just laughted and said I'm being ridiculous. Him writing that song for me wasm special to me but him not remembering makes me feel like it wasn't to him
