Which bridge to cross

I've got two lovers in my life now
a true love and one that's brand new
i'm not really sure that i know how
to love one and tell one we're through
Chorus:
i can't sleep at night, i toss and turn
i keep losing sight of lessons i've learned
i'm standing at the crossroads with just one concern
which bridge to cross and which bridge to burn
I knew this was wrong, i didn't listen
cause a heart only knows what feels right
oh i need to reach a decision
and get on with the rest of my life
Repeat chorus
