[General] He loves a girl/ the girl who doesn't love him.

[arjitsharma]

Can I say the following two sentences to mean differently?
* He loves a girl who doesn't him.
* He loves the girl who doesn't him.

Use 'He loves a girl who doesn't love him' or 'The girl he loves doesn't love him'.

"He loves a girl who doesn't love him."
Your second sentence is very unlikely (even with 'love' in it). There must be billions of girls who don't love him. There might be a context for it though. "All the girls in the class love him but one, and he loves the girl who doesn't love him."

To your actual question, yes, but do you understand what they mean?

PS: Crossed with bhai.

It would be possible to use the definite article if a certain pre-specified person of a group is being mentioned.

There are ten girls in his class. Nine of them love him. One of them doesn't. He loves the girl who doesn't love him!
