What should I do with this thing with my boyfriend?

okay so long story short lately me and my boyfriend havent been talking much becuase his got queit abit on his plate (college work, finding a job). It’s been more than a week now and im finding it extremly hard not speaking to him, he used to come on msn but since his laptop has been broken for some he has to share a computer with the rest of his family which adds up to 8 people so you can imagine how hard it is to catch him online. I called him the other night (he cant call me back because his got no credit) I tried for about 2 hours but it would go straight to the answer machine, the night after I didnt call him, we didnt speak all day yesterday so I thought I’d call him at night but when I called it went straight to the answer machine so I didnt bother calling again. I really miss him I don’t know what to do I never see him online and when I try to call him it goes straight to the answer machine any advice?
