What should Single Whipped Male do?
Life is short, so go for it. Ask her out. Make a move. If she's really not into you, just pass it off as a drunken lapse in your judgement and never speak of it again.
You're obsessed b/c it's a perfect fantasy, not reality. We want what we can't have-once we get it we're usually disappointed. So just enjoy the fantasy & keep your bdrm door locked when you jerk off.
Move out. It's not healthy for you & it's not fair to her to have a stalker in such close proximity. Once you're out, you can make your move--tho you may find that once out of sight, out of mind.
Like the option above, you need to move out. But once you're out, do NOT make a move. Not only does she have a boyfriend, she's your best friend's sister. That would not end well.
