Fell out of love...?

I would assume that it means they no longer love something

Never heard that phrase before, but being out is the opposite of in....

Fell in love. . .
Fell out of love. . .

I imagine that it means they're not in love. Probably just an awkward translation.

I hear that phrase from time to time.

I think it applies to couples who used to be in love before but not anymore.

ur exactly right unos. the term fell out of love was first used... hmm... i can't remember... meh... it was used to describe when a couple literally falls out of love with eachother... it means the love has gone, it is no more... it was not meant to be.
