GF didn't say I love you back to me :(?

She has said it today... But when I dropped her off at home (30 min car drive) she ignored me when is said I love you and instead said see you. I don't know if she even heard me, but yeah :/

She's been having troubled with her friend who she has decided to stop being friends with... So maybe she's just having a rough time with that.
