我忌你忌了整整一个往事我念你念了整整一个悲壮

This user name expresses the deep and lingering feelings one has for someone or something from the past, with an element of pain and sorrow. The person not only avoids ('忌' means to taboo or avoid) certain things because of their shared past but also cherishes ('念' can be interpreted as missing or thinking about) that period full of sadness ('悲壮' implies tragedy or grandeur in a melancholic way), suggesting unfulfilled longing mixed with bitter and noble recollections.
