How do you say " i m regret for what i did to you " in Polish??
"Jestem żalem dla tego co ci zrobiłem"
but what a strange thing to want to say, if you want to say:
"I regret what I did to you."
that would be:
"(Bardzo) żaluję to, co ci zrobiłem." the (Bardzo) is 'very (much)' which may be called for in this kind of situation.
Just call me grammar nazi.
