Why does he always make excuses not to see me?

we used to talk for half a year things ended in April. since then we have hooked up some but it was always drama afterwords so we haven't since July. we don't talk either I guess we aren't really friends but if we see each other out we will say hi. he lives right up the hill from me, when I found out we both moved in this apt complex I asked him to hang out he said he'd come see my place and never did, then I asked him as a favor being a guy around the corner for something he said he'd help me then never did, I had to meet up with him to give him his friends phone and he had someone else call me and get it from me, and now I have to give him something of his friends that I have and he said he'd be home after school and it was cool if I dropped it off and now he's saying he isn't home. he said he will be home later but I have a feeling when I text him later when he said he'd be home he will make an excuse not to see me. why is he being like this? I'm clueless.. I wanna see him I wanna be friends I still like him but I don't know if he knows. help!
