Are financial differences a big enough reason to end a relationship?

My boyfriend and I have been together for 5 years. He is my perfect fit as far as personality is concerned. We are both 25. However, I am very driven and organized while he is very lazy. He works a manual labor job which is very taxing, however the majority of his responsibilities fall by the wayside. He rarely pays bills, has no long or short term goals, saves nothing, and plans for nothing... he makes more than enough money to do these things, but neglects them simply out of laziness. I am not really concerned with adhearing to a set "agenda" for life, but it bothers me that we seem to be coasting along and don't have much to show for it. I would be more than happy to get married and settle down, but he doesn't know what he's doing tomorrow let alone plan to save for a ring/wedding/house/life. Not to mention his complete neglect for financial responsibilites has left his credit score in shambles, while I've been working hard to maintain mine in hopes of getting a house. If I don't go down the "domestic" road, I'd really like to volunteer abroad or at the very least do some international travel. It would be a gigantic strain on our relationship if I left for that period of time, but the liklihood of him saving and joining me is again... slim. I feel that his inability to be responsible is keeping me from moving forward in life, and while I want to work through this with him because I love him and want to be with him forever and think it would be very difficult to find someone I care about as much as him, I really fear that I'm wasting the best years of my life by remaining stagnant. PLEASE HELP!
