how will you know if he/she's the right one?

You can spend time with that person, u might know how and what he is.But i think that before marriage we can't understand him/her quite well.because u usually show ur best behaviour to ur lover . And most of the time we are just blind to c the faults of the one we love. But once married , slowly , things begin to unwind. If u love that person realy , u adjust.After all this is what is life...

spend some time the person you want to know & then decide
