You have been dating for 2yrs.

Mattheo is The dark lords son. He is trying to recruit Mattheo to become a death eater. Mattheo has sworn to protect you.

One day, you are in diagon alley, you pass out. You wake up, tied to a chair, The dark lord with all the death eater behind him, with Mattheo, who now has a dark mark on his forearm.

“ CRUCIO!” Voldemort hits you with the curse, Lucius holds Mattheo down so he can’t look away, he is forced to watch you get tortured.
