<human>: Can you condense the text into three sentences or less?

So basically I really liked this guy who I lived with and it made me act really weird towards him because I couldn't express it to him because we lived together.  I felt a need to seek his approval to show that I wasn't weird or some weird shit like that.  Anyway, so I apologised for being weird, tried to vaguely explain what was going on, how he made me feel crap and the like but he is now ignoring me, despite telling a mutual friend that he is worried about me.  I feel so let down and so ashamed for even liking this guy but I've liked him for so long that I don't know how to stop.  Due to circumstances I haven't seen him for almost 6 months now, and not talked to him properly for like 3 and I still can't get over it.  The worst thing is is that I'm gonna have to see him next year for university and I'm so embarrassed and pissed off about the whole thing I don't know how I'll be able to.  Any advice would be very much welcome.
<bot>: guy ignored me in time of need how do I get myself to say fuck dat bitch and move on but still be able to face him when I have to.
