Cover art for Cumbersome lyrics by Seven Mary Three

Mycohl has it, about the relationship being a stalemate and that a guy is losing his girl, he doesn't know how to get her back even though he probably led the relationship get to that point. I also agree that cumbersome (burdensome) should mean heavy, the bad relationship has become burdensome (or a heavy load) on the shoulders of both the guy and the girl. I've seen weight (meaning negative, excess baggage)used in alot of grunge and post-grunge songs as a common theme, sometimes it means guilt too. I like the way cumbersome is used in this song.
