Yes, what you described can be considered physical abuse. Any intentional act of physical violence or force used against another person, especially during an argument, is not acceptable and qualifies as physical abuse.
Grabbing someone by the chin and shoving them forcefully is a form of physical aggression that can cause physical harm, pain, and distress. It can lead to injuries, bruising, or other harm, both physically and emotionally.
It is essential to recognize and acknowledge such behavior as abusive and unacceptable in a healthy relationship. If you are no longer in a relationship with this person, it's crucial to prioritize your safety and well-being. If you are still in contact with him or feel threatened in any way, consider seeking support from friends, family, or professional resources to ensure your safety and explore options for dealing with the situation.
Remember, no one has the right to use physical violence or force against another person, and seeking help and support can be crucial steps toward healing and breaking free from an abusive situation.
