constant arguing normal?

me & my boyfriend have been together for almost a year now and we've been arguing more than often lately. usually it's roughly twice a week but now it's everyday. and more so about stupid, little things. we had a week where we've spent every day together and it was amazing. after that, we haven't seen each other in about two weeks and everything is just going downhill. he claims he gets really upset when he can't see me. could this just be withdrawal? should i be worried about my relationship?
