So, for a change, I'm the dick that only read the first post and last page. Maybe I missed this.
As someone who also lives with his parents (embarrassing but moving on)... I'm sorry, but even if we've been invested in one another that long, I wouldn't be the most comfortable with bringing you over. In this situation it's not like your my girlfriend, so it's kind of weird to have you over, introduce you to my parents, etc. Worse, it's not like we would actually get to play, which I assume was most of the reason you would have wanted to go over. Playing with parents around is a major major no-no. Absolutely not.
If you came at me with the same sort of attitude and I were really living with family, then yes, I would respond in the same way. No offense or anything.
But then, given the other excuses it's likely that he was lying. Though, it's possible he was just as embarrassed to be living with his parents as I am.
But who knows. I'm just trying to give insight into an alternative point of view.
