My friend say he want to be Buddha,and he force everyone beside him follow Buddha, but we feel that we want to live our own way.

Dear friend, I can understand how you might be feeling frustrated and uncomfortable with your friend's behavior. It's important to remember that everyone has their own path in life and it's not fair for someone to force their beliefs and lifestyle onto others. From a Buddhist perspective, it's important to respect the free will and autonomy of others. The Buddha himself taught the principle of non-attachment, which means that we should let go of our attachment to our own views and allow others to find their own way. From a psychological perspective, it's also important for individuals to have the freedom to make their own choices and live their lives in a way that feels authentic to them. When someone tries to control or coerce others, it can cause feelings of resentment, anger, and even rebellion. It's important for your friend to understand that his actions may be causing harm to his relationships and that he needs to respect the autonomy of others. In terms of coaching advice, I would suggest having an open and honest conversation with your friend. Let him know how you feel and how his behavior is impacting your relationship. Encourage him to explore the principles of non-attachment and to focus on his own path, rather than trying to control others. It may also be helpful to set boundaries and let him know what you are and are not comfortable with in terms of discussing religion and lifestyle choices. Remember, it's possible to have different beliefs and still maintain a respectful and loving relationship.
