Who is the One?

Decided to be with someone,
reason? "convenient" he said, then he was gone.

Disappeared and no goodbye,
hunted by old memories bring tears to my eyes.

What was left was heartaches from old love,
that I am certain, I will never again have.

Then, came along a special someone,
ready to accept me for who I am.

Each moment, each day, he held my hand,
kept me from falling down.

Confused who I should choose?
an old love or special someone which both, I die to lose?
