I love you, I guess

She's saying it just to get you off her back. She probably hates your guts and just wants you to leave her alone. Don't bother her. She'll come back when she's ready to scream at you again.

She's saying it because she's too tired to fight you. She doesn't love you. She just wants you to go away and let her sleep. Don't make her wake up again.

She's saying it because she's too lazy to say anything else. She doesn't love you. She just wants you to leave her alone. Don't be a bother.
