betraying
Penso che la mia ragazza mi stia tradendo.
I think my girlfriend is cheating on me.
Your wife is cheating on you.
Penso che il mio fidanzato mi stia tradendo.
I think my boyfriend is cheating on me.
O Alicia penserà che la stia tradendo.
Or Alicia will think I'm cheating on her.
— L'uomo dei sogni (1989)
Your husband is cheating on you.
