我讨厌自作多情的自己
[wŏ tăo yàn zì zuò duō qíng de zì jĭ]
Here, the person expresses dissatisfaction with their own self, specifically for assuming too much or acting overly sentimental in romantic matters. It can mean an internal conflict where one feels guilty or annoyed about interpreting someone’s friendliness as more than what it was intended to be.
