坑吧？

坑 or not, the protagonist (i.e. LZ) sounds pretty delusional and naive, if not retarded. the break-up message sounds like something written by a teenager. Whether the BF is problematic or not, she definitely isn't someone who knows or appreciates love and being loved yet. there is nothing in this post that makes me feel that the protagonist has a heart that feels joys or pains. it's all her whining about and calculating the situation. i have no sympathy toward such cases. sorry.
