他不爱你何必自作多情
[tā bù ài nĭ hé bì zì zuò duō qíng]
It means 'Why bother having delusions of love if he doesn't love you'. People may choose this name to express self-mockery or helplessness about an unrequited love, suggesting that there's no need for such unwarranted self-confidence or self-deception when facing someone who doesn't have feelings towards you.
