in love with flatmate/best friend

So I'm really conflicted as I think I really like my flatmate (and best friend at uni). Honestly I don't think I've ever felt this way about anyone before. I don't want to tell him as I live with him and if I tell him before summer it could make things weird next year as we're not living together and potentially the friendship could just become awkward but I really value him as a friend! Certain things make me thing he could potentially like me back but at the same time he acts this way around other people sometimes too. I've liked him for around 8 months now which is crazy but potentially just because I live with him so it's hard to get over! Ahhh
