New Years Boy

Ive been talking to this guy since New Years, so its been a while since its now the end of October. At first we were just hanging out and enjoying each other's company. Then Marchish, he told me he doesnt want to be in a relationship with me and gave me reasons why which i proved later were untrue. So I was like yeah okay whatever. But we still spent the night with each other, did homework together, went grocery skipping, etc etc etc... We acted like a couple. Fast forward to my May birthday, he didn't tell me happy birthday. cool. ouch. Upset. But, whatever. I forgave him because I'm dumb. Blah blah blah. the jist is... We still act like a couple when we're together. we even say i love you sometimes. but he still doesnt want to be in a relationship with me. so what do i do?!? also: ive tried talking to other guys and i just always go back to him. weve tried just being friends too. both of us have tried ending it but neither one of us can follow through. he still doesnt want a relationship but now he says the reason is that he's in school...

UPDATE: I ENDED THINGS WITH HIM ALTOGETHER AND AM NOT DATING SUCH AN AMAZING BOY AND AM EXTREMELY HAPPY
