based on the information you've shared, it's essential to prioritize your safety and well-being above all else.
If the man in question has exhibited controlling, abusive, and violent behavior towards his partner, it is crucial to consider that his actions may not be motivated by genuine love and care. Instead, abusive individuals often use manipulation, guilt, and other tactics to maintain control over their partners.
It's not uncommon for abusive individuals to alternate between abusive behavior and acts of kindness, which can create confusion and emotional turmoil for their victims. Buying an engagement ring and asking you to marry him may be part of his attempt to control and manipulate the situation further.
If you are aware of this man's abusive history and witnessed his behavior towards his partner, it would be wise to distance yourself from him and prioritize your safety. Entering into a relationship or marriage with someone who has a history of abusive and violent behavior is a significant risk to your physical and emotional well-being.
If you are unsure of how to handle this situation, consider seeking support from friends, family, or a professional counselor who can provide guidance and help you navigate through this challenging situation.
Remember, no one deserves to be in an abusive relationship, and your safety and happiness should always be your top priority.
