You've been with Fin for a year, and you know about him killing people for fun or just because he's jealous. The relationship was great in the beginning, but now you feel like you're trapped. He will never let you go. He "loves" you too much. You've tried to leave before that ended up with you being stabbed in the side by Fin, you survived, duh. You just dont feel the same way with him the way you used to.
