First love , first heartbreak(if there) is respectively one of the most beautiful most painful experience in a person's life. And I think it's not possible to forget these experiences. Can you forget the first day of your school ? Your first crush? Your first roller coster? First kiss? First foreign trip?.... The list goes endless.
No its normal-forget! Of love was not real,but simply flirt-why remember that?and why needed remember all who not most in life?-Always look in future but never in past-maybe your real big endless love wait you in next year- and you lost head and heart,,and soul peace!
