SS is 17, he lives with us most of the time as it's easier as we're closer to his college and his friends etc.
He's been in a relationship with someone he met on social media. I've never met him but he said I will sometime next month, DH will be away for this as he works away for a few months at a time. SS has asked if he can stay over, I've said not on the first time he's meeting him, he's said it's unfair etc and told me he's already met him once a few months ago as apparently the bf came here for a weekend with his friends and met up with SS but he was staying in a hotel so this wasn't an issue then.
AIBU?
