Be my valentine?

I always said that if i had the chance
well, i would do it all again
but that would mean having to trade now
for all the things that i had then
yes i could change all that happened
erase all the pain I'd ever been through
but then i wouldn't be where i am rite now
and i would never have met you
everything happens for a reason i guess
and for that, i am so glad
because i would never trade you babe
for all the things that i had
in the end it'll all work out just right
things will always be the way they're suppose to be
and right now in my life I'm sure
that its you who's supposed to be with me
so although life can change in an instant
people can come and they go
lets just make the best of today
because you just never know
and if tomorrow's sun rises
and i find that you are not mine
then answer me today just this baby
will you be my valentine?
