If you're not still crying after season 2 episode 18 'Awake, Arise, Or Be Forever Fallen' then you have a heart of steel. Malec has been through so much over the past two seasons. How many times have we seen them come close to losing each other forever? And now, just when their relationship seemed stable, we have to go through the break up of the century.
We can understand why Magnus felt betrayed by Alec.
He thought his boyfriend would always be honest with him. After finding out about the Soul Sword he felt he had to put his people first and form an alliance with the Seelie Queen.
And Alec knew he had made the wrong decision.
We could all see how much he regretted lying to Magnus. Even Izzy couldn't make him feel any better about what happened.
But, while Alec was distracted by events at the Institute, Magnus spent time thinking about their relationship.
He looked back at his earliest memories of meeting Alec.
The first time Malec really connected was when Alec offered the Warlock his strength to heal Luke.
Remember in season 1 episode 6 they shared cocktails and there was an instant spark between them? Or the next episode when Alec admitted to Izzy that he spent the night, but that nothing intimate happened? Of course you do, how could you not.
When they took the next important step in their relationship it was a really big deal.
We knew from to season 2 episode 7 that Alec had never even been with anyone in that way before and Magnus was still vulnerable from past heartbreaks, but we loved getting to see more of this moment between them.
Magnus was worried that Alec wouldn't accept him.
Many Shadowhunters (including Alec's parents) don't see Downworlders as their equals. But Alec never felt that way about Magnus.
Even while they were taking some time apart, Magnus still came to Alec's aid in a time of crisis.
He knew how much Max meant to his boyfriend, and Magnus would never let an argument get in the way of saving someone's life.
He tried to comfort Alec when they realized the Silent Brothers would have to perform a risky procedure on Max.
And for a moment we thought everything would work out.
Magnus remembered being intimate with Alec after that special night.
They had shared some of their deepest fears with each other. This was an emotional step that was just as important as the physical one.
And they spent many more nights together after that one.
We all remember Magnus talking about Alec's adorable little snores.
After Max got the all-clear, Alec finally tried to talk to Magnus about their relationship.
After everything they had been through he thought they could weather the storm.
He apologized for hiding something so important from his boyfriend.
Magnus understood why Alec did it, but he couldn't get over the betrayal.
Magnus realized that the Seelie Queen was right, and he had to put his people first.
This is something that he must have also learned from Alec, who has almost always put his duty as a Shadowhunter before anything else.
Magnus said goodbye, leaving Alec looking completely shell-shocked.
The break up hurt both of them, but it absolutely destroyed all of us Malec fans. This was literally our worst nightmare come to life.
