(I love you, I love you more, I love you times infinity)
Wow. You got sold short. Maybe someone got drunk, and got the surtitles mixed up with some other opera?
Here's an actual translation. It;s a bit more interesting.
TOSCA (bursts in with a kind of violence, thrusting Cavaradossi aside as he tries to embrace her, and looks around suspiciously) Why was it locked?
CAVARADOSSI That was the sacristan's wish.
TOSCA With whom were you talking?
CAVARADOSSI With you!
TOSCA You were whispering with someone else.
Where is she?...
CAVARADOSSI Who?
TOSCA She! That woman! I heard her quick steps and her dress rustling.
CAVARADOSSI You're dreaming!
TOSCA Do you deny it?
CAVARADOSSI (trying to kiss her) I deny it and I love you!
TOSCA (with gentle reproach) Oh no! Before the gentle Madonna, no, Mario! First let me pray and offer these flowers. (She approaches the Madonna, arranges artfully about her the flowers she has brought, and kneels to pray; then rises to address Mario, who has resumed his work.) Now listen: tonight I am singing, but the programme will be brief. Wait for me at the stage entrance, and we two shall go alone together to your villa.
CAVARADOSSI (his thoughts still elsewhere) Tonight? TOSCA It is the time of the full moon, when the heart is drunk with the nightly fragrance of the flowers. Are you not happy?
CAVARADOSSI (still somewhat distraught and thoughtful) So very happy!
TOSCA (struck by his tone) Say it again!
CAVARADOSSI So very happy!
TOSCA How faintly you say it! (sits on the steps next to Cavaradossi) Do you not long for our little house that is waiting for us, hidden in the grove? Our refuge, sacred to us and unseen by the world, protected with love and mystery? Oh, at your side to listen there to the voices of the night as they rise through the starlit, shadowed silences: from the woods and from the thickets and the dry grass, from the depths of shattered tombs scented with thyme, the night murmurs its thousand loves
and false counsels to soften and seduce the heart. Oh wide fields, blossom! And sea winds throb in the moon's radiance, ah, rain down desire, you vaulted stars! Tosca burns with a mad love!
CAVARADOSSI Ah! Sorceress, I am bound in your toils...
TOSCA Tosca's blood burns with a mad love!
CAVARADOSSI Sorceress, I will come!
TOSCA Oh, my love!
CAVARADOSSI (looks towards where Angelotti went out) But now you must let me work.
TOSCA You dismiss me?
CAVARADOSSI You know my work is pressing.
TOSCA I am going! (Glancing up she sees the painting.) And who is that blond woman there?
CAVARADOSSI Mary Magdalene. Do you like her?
TOSCA She is too beautiful!
CAVARADOSSI (laughing) Ah, rare praise!
TOSCA (suspicious) You laugh? I have seen those sky-blue eyes before.
CAVARADOSSI (unconcerned) There are so many in the world!
TOSCA (trying to remember) Wait... wait... Its the Attavanti!
CAVARADOSSI Brava!
TOSCA (blindly jealous) Do you see her? She loves you! Do you love her?
CAVARADOSSI By pure chance...
TOSCA Those footsteps and whispers... Ah... She was here just now...
CAVARADOSSI Come here!
TOSCA The shameless flirt! And to me!
CAVARADOSSI (serious) By pure chance I saw her yesterday... she came here to pray... and I, unnoticed, painted her.
TOSCA Swear!
CAVARADOSSI I swear!
TOSCA (her eyes still on the painting) How intently she stares at me!
CAVARADOSSI Come away!
TOSCA She taunts and mocks me.
CAVARADOSSI What foolishness! (holding her close and gazing at her)
TOSCA (insisting) Ah, those eyes...
CAVARADOSSI What eyes in the world can compare
with your black and glowing eyes? It is in them that my whole being fastens, eyes soft with love and rich with anger... Where in the whole world are eyes to compare with your black eyes?
TOSCA (won over, resting her head on his shoulder) Oh, how well you know the art of capturing women's hearts! (still persisting in her idea) But let her eyes be black ones!
CAVARADOSSI My jealous Tosca!
TOSCA Yes, I feel it, I torment you unceasingly.
CAVARADOSSI My jealous Tosca!
TOSCA I know you would forgive me if you knew my grief.
CAVARADOSSI You are my idol, Tosca. All things in you delight me: your storming anger and your pulsing love!
TOSCA I know you would forgive me if you knew my grief. Say again those consoling words... Say them again!
CAVARADOSSI My life, my troubled one, beloved. I shall always say: "I love you, Floria". Set your uneasy heart at rest, I shall always say: "I love you".
TOSCA (disengaging, lest she be won completely) Good heavens! What a sin! You have undone my hair.
CAVARADOSSI Now you must leave me!
TOSCA You stay at your work until this evening. And will you promise that, blond locks or black, by chance or otherwise, no woman shall come here to pray?
CAVARADOSSI I swear it, beloved. Go now!
TOSCA How you do hurry me along!
CAVARADOSSI (mildly reproving, as he sees her jealousy return) Come, again? TOSCA (falling into his arms, with up-turned cheek) No, forgive me!
CAVARADOSSI (smiling) Before the Madonna?
TOSCA She is so good! But let her eyes be black ones! (A kiss, and Tosca hurries away. Cavaradossi listens to her withdrawing footsteps, then carefully opens the door half-way and peers out. Seeing that all is clear, he runs to the chapel, and Angelotti at once appears from behind the gate.)
