Forever is actually FOREVER, for
girls.
But for guys it means in
reality 4-6 months or until he finds someone
better.
But: Once in a while you DO find those guys, (only about 3% of guys are like this) that DO mean forever.
Girl:
I love you until
death do us part, always and forever.
Boy: I love you forever until a 20 year old with her clit pierced comes along.
