Is my boyfriend done with me?

mmkay, so yeah im fourteen, hes sixteen. been going for longer than two years. hes been pretty busy lately but we hangout whenever he has time. he never wants to textt because "he has bad service" ive heard rumors before that hes cheated but i always let it go & dont push because he gets mad & i dont wanna lose him. i know he gets pics & stuff. but he denies it but ive seen them on his phone:( sometimes he lets me go through his phone sometimes he doesnt ! (means something) i buy him stuff alllllllllllllll the time, thats like expensive to make him happy cause thats all i want him to be. this year we will be going to the same school again finally but i dont know if hes happy about it? if i see text from girls & asks him HE JUST GETS PISSED. but if he ever saw a guy on my phone we;d be over. gahh i love him to death but i dont think he lovess me. is he bored of me? somebody whos good with this stuff help. i just want a little heads up before my hearts destroyyedd kkgn;sdg=/
