You are a tricky little man. You met a young woman who was sweet and had been taken advantage of before and found her easy prey. You picked pieces off of her hoping she would simply break and stop struggling against your control. You played your parts well. You turned what should have been a healthy D/S relationship in the bedroom into a nightmare where you punished her in real life every day for not being who you wanted her to be. She didn't let that last bit of her light disappear though, she held on to it and kept it glowing. She got away from you and is a better person for it.
There will be long nights ahead where she remembers how the decisions she ended up making were a survival response to what you wanted. She will wake up and not be able to breathe wondering what you might say to break her down that day. Then the relief of knowing your hate cannot infiltrate her soul anymore will wash over her. You are an angry little man and I pity you.
