boyfriend help

thank you I dont feel like im totally obsessed now, the first time after three days he txted me and I tried my best to let him no that I was mad about it and he sayd he felt terrible about it, I told him it was ok but he sayd that it wasnt and that he should of have known better. the next day he came over to my house and he told me he was verry sorry and that know he knew it bothered me when he didnt call me. then I kinda felt bad about making such a big deal about it. he went off on vacation for a week and we txtd during the week but when he came back again he didnt call me or txt me and he sayd that he was sorry and that he had to go to drives ed which took all three days but he got out of drivers ed around four in the afternoon he could have taken 5 minuts to call to at least say hi. and when he says he misses me all the time I want to freak out and yell at him to stop telling me things he really didnt mean. but I mean at first I beleaved him when he told me thinks like that but now I kinda feel bad when he says things like that to me because I feel like he is lieing to me. sorry this is so long but I really need some opinions on this and I dont have any girlfriends I can talk to. please comment
