The girl is having bad times, probably a boyfriend.
So she goes to this guys house for help, and he lets her.
Something happens and he wonders if it's alright that he's doing this even with her ex.
Which is why she said everything was a mistake. But he kinda saw that coming, apparently.
But he figures they can't last.
And she said maybe, just maybe you won't end up like him.
^ Maybe these two can work out, happily.
Unlike her and the other guy (hence: unhappy)
