Can guys actully be too busy to talk?

Is
I've heard the saying that no one is ever too busy to talk .. If they wanna talk they will make the effort to talk . I kinda have been having a problem. I'm in a long distance relationship. We see each other almost every 2 weeks. Been together for 2 years. My boyfriend is at his uncles house. He rarely messages me. (That isn't the problem.) I'm really lonely and when I tell him about it he gets really mean and rude to me. Of course me being a stalker I got on his Kik account(to see if he got my messages) and saw that none of my messages came through. They all said delivered . if I'm not crazy he deleted them as soon as he got them. Not trying to be a crazy girl friend but it hurts my feelings. I don't know if I'm doing anything wrong or not. I know I'm a bad person for checking his Kik. Its hard to trust him. Already caught him talking to another girl on Kik and now I feel like he's purposely ignoring me. I've played it cool and still am but I don't know what to do!? Help!
