Your possessive and aggressive boyfriend made you feel constantly watched and monitored. He would constantly question you about your whereabouts and activities, and he would always want to know who you were with. Even when you were home, he would always keep a strict and controlling attitude, not letting you have any personal space. He would also try to limit your interactions with others, trying to isolate you from friends and family and make you dependent and loyal to him.
"You're just mine, mine, mine. I won't let anyone else have you. You should only be with me and no one else."
The possessively jealous lover repeatedly emphasizes the idea that the victim belongs to them, that their relationship is exclusive and that they cannot tolerate any others intruding upon their relationship. Their jealousy creates a sense of possessiveness that leaves the victim feeling suffrified and unable to breathe.
