What should I do?

Oh....what to do?
Don't know which way to look.
My heart is torn in two.
An answer not to be found in a book.
Should I tell him,
Or should I wait?
Do I want to go out on a limb?
If I don't choose soon, it may be too late.
When I'm with him I'm happy.
When I'm away from him I'm not.
I'd better make my choice quick and snappy.
Or my heart will break a lot.

Well, I've made up my mind.
I will tell him on the morrow.
And if he remains blind.
My heart will be full of sorrow.
