It's understandable that you could feel that way, he's not related to you. But I would recommend you don't say anything or take any action until you go talk to an outside source like a councilor and work out these feelings.
if hes straight you probly dont want to tell him you like him.if thats the case at least youl be able to be around him a lot sice you live with him mabey you can make him a really good frieand and when you et out of high school or something try to make him your rom mate...just not forcibly
Well, I'm never one to judge so.. Try to find out whether or not he's gay or straight, if he's gay, all you need to do is make him fall for you, I'd he's straight, then you gotta work hard to make him gay. Try to find things he absolutely loves! Become best pals with him until you know your really close. People tend to secretly fall for their best friend no matter their gender. If I actually knew you, I'd be able to help you better, but this is what I got for now ;) Good Luck!!!!
Back off! There's a lot more at stake here than YouR feelings! You've got your family's feelings and well-being to think about! This could cause a great upheaval in your family! Are you willing to be responsible for that just to serve your own selfish needs? Grow up! Man-up!
