I Should Be Really Happy But I'm Not... Because Of Him?

My boyfriend and I haven't been talking for a week, he says it's because he's too busy with school and work. But he went 3 days to me without seeing me between classes or walking me to my bus, calling me, or even sending me a single text. When I asked him what was up with that he wrote me this long text saying how stressed he was with school and stuff and he doesn't have time to talk. So I'm like ok well talk to me when you can. It's about to be day 3 again and still nothing... We've been going out for 6 months and I don't want to just end the relationship but this whole month has been kind of sh!tty. But I can't picture being without him. Nothing can make me happy, being with my friends, I just got a job, getting a new motorcycle in like 2 weeks, I just finished my last day of high school today... but yet none of that stuff makes me even close to happy... All that stuff means nothing to me without him... ):
