All your masks (слэш)

Based on the prompt: Tony breaks up with Loki: "I can't do this anymore". He's tired of the hiding/lies & how it's always a battle. His heart hurts & he's exhausted. Is Loki's reaction a possessive 'too bad I won't let you go'? A angry rage where he blasts Tony across the room and feels horrible after? Or faced with losing Tony, he slips into Tony's room a few nights later, kneels beside the bed & lets Tony see every mask is SHATTERED. He's the closest to begging for a second chance he could ever get. Happyend?
