he claims he really doesn't like me but his behaviors don't tell the same story?

so he's saying that he doesn't like me etc like at all... we didn't speak for a while up until late May, he begged me for another chance, made a fake account on fb and everything to try and get me to talk to him... told me he would gain my trust back... I got tired of waiting so in mid July I got rid of him, ended up trying to get him to talk to me about 2 weeks ago ended up adding me on snapchat, he sat there one night saying he doesn't want me to see, then he starts saying how he's afraid I'll try setting him up again (was meant to be just a scare to scare him out of doing drugs, nothing even actually happened) and said I hurt him and his friends a lot... yesterday he was feeling really rough cause he was on a lot of drugs apparently the night before... he got mad when he thought I didn't really care, but when I said I did, he kept saying no I don't, told him I'd always be there for him as long as he wanted me to be and he said he didn't... the minute we start getting along, he quickly jumps back to his defensive self again... it's confusing. help?
