Problem No. 3: You can't agree on finances. For couples that are in the early stages of living together, figuring out how to deal with money can be incredibly stressful. Arguments can arise from all sorts of situations, but staying organized and being honest can help prevent a lot of them.Have a shared space where both of you can access all of your financial information. Whether it's a drawer, a file cabinet or an entirely separate desk, make sure that it stays organized. Create a system that both of you agree on and stick with it. Place budget goals in a highly visible place. Write down both of your financial strengths and weaknesses and keep each other accountable. Decide who is responsible for which bills, then write everything down and post your notes in a visible place. Get a calendar and make sure you each know when the bills need to be paid.
