i dont understand what you would be offended about? does he not want you to go?

personally im captain paranoia over here and would automatically think the worst because most guys i come into contact with are assholes.....but anyways lol

if you trust him though i dont see any reason why you would be offended? it probably just came out wrong and he probably honestly doesnt want you to feel bad. but hey, theyre gonna be your family too, right? so if you want to go you should go y'know.
