why does it happen?

we doubt the person we are with.
there comes a time where we wonder if we can be with them forever.
no matter who it is.
because we dont get along with any one person perfectly.
so who is the right person?
can we ever be satisfied?
i feel like we will never be satisfied with the person we are with.
because we doubt it.
and that crazy love fades.
and it never comes back until you are falling in love with someone else.
and then that fades.
its this continuing cycle.
its not a comforting thought, whatsoever.
