Physical abuse involves the use of physical force to harm or control someone. From your description, it seems that your partner's actions of shoving you and taking your keys to prevent you from leaving during an argument could be considered physical abuse.
Abusive behaviors can take many forms, including physical, emotional, psychological, and financial abuse. It's essential to remember that any form of abuse is not acceptable and should not be tolerated in a healthy relationship.
If you find yourself in a situation where you feel unsafe or uncomfortable, it's crucial to prioritize your safety and well-being. Consider seeking support from friends, family, or professional counselors who can provide guidance and assistance. Additionally, there are organizations and hotlines available that can offer resources and support to those experiencing abusive situations.
Ultimately, if you believe you are experiencing abuse, it's crucial to take steps to protect yourself and explore options for leaving the situation if necessary. Remember, you don't have to go through this alone, and there are people willing to help you.
