Has he met your friends and have you met his?
Before committing to a guy, you should always make sure that you’ve introduced him to your friends, and more importantly, that you’ve met his friends as well. Why?
Because if he’s unwilling to introduce you to his friends, this could be a huge red flag because there is probably some (shitty) reason behind it, and you definitely don’t want to commit to such a person.
If you’re going to be his girlfriend, you want to make sure that he will treat you like one.
