Yes, it is wrong for your mom or anyone else to physically abuse you for any reason, including having a boyfriend. Physical violence is not an acceptable way to express disapproval or enforce rules. Everyone has the right to be treated with respect, dignity, and without violence or harm.
Healthy parenting involves open communication, setting boundaries, and providing guidance, but it should never involve physical violence. If you are facing such abuse, it's essential to seek help and support from a trusted adult, family member, teacher, counselor, or a local support organization.
Depending on your age and where you live, there may be legal protections against child abuse, and you have the right to be safe. Don't hesitate to reach out for help to ensure your safety and well-being. If you feel unsafe talking to someone close to you, consider contacting a helpline or support organization that specializes in child abuse or domestic violence. They can offer advice and resources to help you in this challenging situation.
