Im confused , what should i do?

I like this boy and he likes me but hes a player well dats wat people say but i dont really trust him . we've been liking eachova for like a year but we seperated since the relationship made me a bit confused . we've come back together but hes not acting the same he still claims he loves me and every thing and having moodswings . when i asked him he said he feels like ive used him dat wen i feel like dating i come back to him , i tried to explain but he didnt reply wen i sent him a message and he's not replying . i cant meet him becuz im on holiday nd i really love him and dont want to split up what should i do if he doesnt want to listen to my messages and i cant stop thinkin about him =(
