What's going on here? please answer.?

So last year we all went to a new school and there I met kaylii, natasha and Eric. well eric was kaylii and natashas best guy friend and he realled liked kaylii and a girl named Harmony and they both turned him down. I fell hard for him and he fell hard for harmony. tasha and kaylii told him I liked him and he said I was to quiet for him and i started talking more and I was at kayliis and he was bein really flirty. and it waz just me kaylii and eric. then I saw him wen we were bowling and at orst he ignored me then he started bein kinda weird and then we moved up a grade and I was sitting with harmony and him and a few of our girl friends and he ignred me, I found out him and harmony were going out and I waz happy for him because last year he really really liked her. and he doesn't talk to me but wen I'm talking to kaylii he keeps walkin up to us, ignoring me and telling her random things. and in science he walked up next to me wen I was with kaylii and brushed against my arm with his arm and stood there and walked away. then I was taking a test and he tapped me and walked away. so does he like me? does he not like harmony as much? why was he ignoring me this summer and the beggining of this year? why does he randomly come up to me and kaylii? we talked a lot at kayliis and on the last day of school and at the bowling alley...I miss that. what happened?
