Yes, it is abusive behavior if your boyfriend takes your car keys and prevents you from leaving after a fight, regardless of the reason he gives. This action is a form of control and manipulation, which is not acceptable in a healthy relationship. Taking away your ability to leave a situation when you feel unsafe or uncomfortable is a violation of your autonomy and boundaries.
In a healthy relationship, both partners should respect each other's boundaries and allow each other the freedom to leave and disengage from a situation if they feel the need to do so. No one should be forced or coerced into staying in a place they don't want to be.
If you find yourself in such a situation, it's important to recognize that this behavior is not acceptable and can be harmful in the long run. If you feel safe doing so, communicate your concerns and feelings to your boyfriend, and let him know that such actions are not acceptable. However, it is essential to prioritize your safety, and if you feel uncomfortable or unsafe, consider reaching out to a friend, family member, or a support helpline for assistance.
If this kind of behavior continues or escalates, it may be necessary to reevaluate the relationship and consider seeking help from a professional counselor or support organization specializing in domestic abuse or unhealthy relationships. Remember, your safety and well-being are paramount, and you deserve to be treated with respect and kindness at all times.
