Why am i feeling sad when i should be happy?

well, i have a wonderful boyfriend, but right now. im kinda feeling like he doesnt like me anymore. hes supposed to come over tomorrow, but i dont know. i dont love him cause we havent been dating that longgg, but i really REALLY like him, he was the one that made me start over, and forget about the past. but i dont know, me and him akways talk on the phone right now till one of us falls asleep, but he hasnt texted me, or called me. and hes been on facebook, and didnt message me back. but i meann, im pretty sure he still cares, so why am i feeling this wayyy?
