Controlling behaviour is often disguised or excused as concern. Concern for your safety, your emotional or mental health, the need to use your time well, or to make sensible decisions.
Your abuser may be angry or upset if you are 'late' coming back from work, shopping, visiting friends, etc., even if you told him/her you would be later back than usual.
Your abuser may question you closely about where you were, whom you spoke to, the content of every conversation you held, or why you did something he/she was not involved in.
As this behaviour gets worse, you may not be allowed to make personal decisions about the house, clothing, going to church or how you spend your time or money or even make you ask for permission to leave the house or room.
Alternatively, he/she may theoretically allow you your own decisions, but penalise you for making the wrong ones.
At the beginning of a relationship, an abuser will always say their jealousy is a sign of love. They may question you about whom you have spoken to or seen during the day, may accuse you of flirting, or be jealous of time you spend with family, friends, children or hobbies which do not include him/her.
As the jealousy progresses, he/she may call you frequently during the day or drop by unexpectedly. They may be unhappy about or refuse to let you work for fear you'll meet someone else, check the car mileage or ask friends to keep an eye on you. Jealousy is not proof of love, it is a sign of insecurity and possessiveness.
