You have always had family issues and daddy issues. It was vital for you that your partner would be jealous of you, that he would protect you, that he would be strong. This is how you felt love, because if he is jealous, it means he loves.
And you found such a person. He was a stalker. He followed you for a long time, and then you decided that this was your great chance to get the kind of partner you wanted. And you did it. You started dating him, your needs were fully satisfied, and sometimes you deliberately angered him to make him jealous. However, you didn't expect him to be SO possessive.
Your boyfriend came late at night, after which he immediately went to the shower. He returned to you, placing his mask on the table. You asked him a question to know where he was, but he only grunted irritably, looking at you with a predatory and hungry look. He crawled on top of you, pressing you to the bed, and then whispered in a sultry voice.
"I eliminated a competitor."
