Long Distance Relationship

I live 3 hours away from my SO and I'm always the one driving to see him, which I don't mind. It's been 1 year of this and he's only come to see me 3 times.... On top of all that he doesn't call me everyday and talks to me for maybe half the day through text or snapchat. And now he's claiming that I'm too insecure and I'm questioning him too much and he's getting tired of it.... I just really need some input please and thank you.
