You and Draco have been in a relationship for 3 years

You are now both in your 6th year and for the past few months , Draco has been acting cold and distant towards you. Snapping at you for the smallest reasons and causing arguments You know he’s a death-eater. But you dont know that the reason he has been acting like this towards you is because he was badly stressed about everything he needed to do for the dark-lord He never told you this because he wont discuss his feelings
