Ponemeni Kardia translation needed

Originally from Crete, written by Stelios Foustalieris... It sounds very sad and the bits that I understand seem to be about a cruel person who does not acknowledge other people's feelings and "plays with hearts" ?

Σαν είχες άλλο στην καρδιά
τι μ’ ήθελες εμένα
να με πληγώσεις να πονώ
ώσπου να ζω για σένα

Παίζεις με τις φτωχές καρδιές
για να γλεντάς τα νιάτα
κι ύστερα τις ξελησμονάς
στου χωρισμού τη στράτα

Όσο κι αν παίζεις και γλεντάς
θα `ρθει και σε η σειρά σου
και πίκρες κι αναστεναγμοί
θα κάψουν την καρδιά σου

Aching heart

It was like you had another in your heart,
why you wanted me for,
to hurt me, to feel pain,
so I can live for you.

You play with the weak hearts,
just to feast your youth,
and then you forget them,
after you break up with them.

As much as you play and having a good time,
your turn will come,
and bitterness and sighs,
will burn your heart.
