What's happening to me?

I saw yet another man who looks like you I thought I was seeing you till my mom saw it too He was standing with a pretty lady Sliding the hair behind her ear, showing off I feel so blue I can't stop falling for you Every passing day, I smile, blushing My cheeks pink, red and flushing I miss your smile, your eyes, your laugh The dimples on your cheeks, so cute I begin to cough You are handsome and I am beautiful But let's not focus on looks Maybe you'd be different Different from the man I read in books
