Advice Please

My boyfriend and I have been dating for almost 3 months now. We were friends before we started dating and kind of started off really fast. We go to the same college but we work a lot and we barely get to see each other between classes, let alone outside of school. He's been a lot busier than I, meaning he has less time to talk and I have more time to think. I've been worried about him and his stress, but I'm also worried about myself. I thrive on words of affirmation and he's very reserved, meaning he doesn't compliment me or tell me that I'm doing a good job. He's a super sweet guy, don't get me wrong. But I like getting and giving attention and I haven't gotten or had the chance to give either. I feel more like we're friends who barely talk and kiss each other good bye before classes. I have no idea what to do and I fear that talking about taking a break to try and figure things out or breaking up would make things more stressful for us both. Please help...
