Plase tell me what I have done wrong here?

Uhm i have been talking to this one guy (for a month now) that says he likes me very mutch. He have said he loves me and so on (and i loke him too so we went into relationship last night) but there is this one weirs thing that whenever i suggest to call eachother he at first would agree on the time but then when the time comes up he is just coming up with different reasons for not to call (like going to shower, then drying his hair l, then he bunt his hair) and now it has been a few hours since he last texted and he is not reading any of my texts. There was this one time were he was the one that wanted to call but at that time couldn't talk and had personal reasons, i still said that i can't talk and the subject was down but i think he might be getting back at me for it? Should i be worried that he is playing with me or what is wrong with me? Maybe all the love letters and stuff were all fake and just to make fun of me? Plase help. Im very confused.
