You’re delusional if:
You think because you’ve met his friends and family the two of you have something. Let me ask you a question, when you met his family, did he introduce you as anything other than a friend? Did he make sure to introduce you to everyone or were you kind of just like everyone else at the happy hour, just happy to be there. Well then why are you using this I met his family and or friends rationale to explain why the two of you might have something. You don’t, what you have is a friendship with benefits, nothing more nothing less.
