Though he hasn't done anything wrong, people/friends in my class have mentioned him being "obsessed" with me and me being his favourite and someone said he acted "creepily" with me. I honestly can feel an unavoidable attraction between us. He has never acted inappropriately towards me but perhaps in a flirty way... once someone said they didn't like his tie and I agreed so he took it off, he once said I was 'one step away from being on the naughty table' and then asked if 'that excited me', he has nicknames for me, he waves at me in the corridors, if I am off school he always asks if I'm ok, he's asked me to his office a few times and once when we were alone he touched my shoulder and looked into my eyes for maybe 30 seconds... when he is teaching he always looks at me for prolonged time periods and asks me questions, when there was a fire drill he told me to walk in front of him so he knew I was safe, on a non-uniform day I wore a low cut top specifically for him and he spent most of the lesson standing behind me 'reading over my shoulder'/looking down my top, once he gave me his jacket because I was cold, he drew a ;) on my work etc
Other students have asked me why he likes me so much, why he acts so weirdly etc. I love him with all my heart and would do anything for him, does he know this and is just trying to take advantage of me? Is he oblivious? Is there just sexual tension neither of us can do anything about?
