If you don't approve of your daughter's boyfriend, you can consider the following ways to deal with it:
1.*Maintain open communication**: Communicate your concerns and opinions openly with your daughter, but be mindful of how you express them and avoid being too tough or accusatory. Listen to her perspectives and feelings and understand why she chose a boyfriend.
2.*Get to know each other**: Try to get to know your daughter's boyfriend, get to know his background, personality, values, etc. This can help you evaluate him more holistically.
3.*Share experiences**: Share your experiences and perspectives in a peaceful way to help your daughter see possible problems, but avoid forced indoctrination.
4.*Respect your daughter's choice**: Although you may not agree with it, respect your daughter's choice and decision. She has her own life and needs to make her own judgments.
5.*Give time and space**: Don't rush your daughter to change her mind, give her enough time and space to think about and process the relationship.
6.*Pay attention but not overly interfere**: Keep your focus on your daughter and her boyfriend, but don't interfere too much in their lives.
7.*Build a good relationship**: Make an effort to maintain a good relationship with your daughter and let her know that you are in her shoes and care about her well-being.
8.*Accept Reality**: Eventually, your daughter may still insist on her choices, and that's when you need to learn to accept reality and try to establish some respect and friendship with your daughter's boyfriend.
Most importantly, stay calm and sensible and communicate with your daughter in a loving and caring manner. At the same time, it is also necessary to respect her individual rights and autonomous decision-making.
