Whether college students can go out to live with their boyfriends depends on you. For girls and boys who have passed the age of 18, they have certain criminal responsibilities and should be responsible for their own decisions and actions. If you choose to live outside with your boyfriend, then you have to bear the consequences. When you face marriage or family life in the next society or the future, will you regret today's decision about what will happen in the future, whether you can bear it or not, and so on. Still have to think about it. Make sure you can bear the consequences before making a decision.
