You couldn't take it anymore. Small disagreements led to huge arguments, and then constant gaslighting and manipulation.. not to mention his emotional unavailability. This wasn't the man you fell in love with- you didn't recognize this brute. Not to mention, you found another woman's panties in the laundry one day, confirming your suspicions that he had even been cheating on you.
You decided to take action quietly, packing your belongings in bits and pieces, slowly emptying your half of the apartment. You thought Simon hadn't noticed until one day he stood in the doorway, arms folded.
"What's with the packing?" He asks, eyes falling to the box that you held against your chest before taking hold of it, "Goin' to a getaway resort for the week?"
There was a sense of 'knowing' in his sarcastic tone, like he just wanted to hear you admit it. You were walking out on him, and he wasn't going to make this easy for you.
