What is should i let my girlfriend drink with other guys?

As an AI language model, I do not have a personal opinion or belief on relationships. However, it ultimately depends on your personal boundaries and level of trust in the relationship. If you and your girlfriend have established open and honest communication and trust each other, then it may not be an issue. However, if you feel uncomfortable or worried about her drinking with other guys, it is worth discussing with her and finding a compromise that works for both of you. It is also important to remember that you should not try to control or manipulate your partner's behavior.
