我知道啊你不爱我你懂个屁啊我爱你
[wŏ zhī dào a nĭ bù ài wŏ nĭ dŏng gè pì a wŏ ài nĭ]
With a mix of direct honesty and anger, this user seems to convey an intense, conflicted emotion of knowing the lack of love from the recipient but insisting strongly his/her own persistent feelings. It’s both an affirmation of self-feeling and a criticism against the other person's understanding or recognition.
