<prompt> Human: Me and my longtime girlfriend are buying our first house. We both are comfortable with slitting bills 5050. Currently I pay the rent as well as all the bills and she gives me cash at the end of the month. Would it be a good idea to open a joint bank account to pay mortgage house insurance bills ect. Or for us to keep the current way were doing things. Any advice would be appreciated  <response>: Unmarried, live with my boyfriend. No way I would buy a house with him before we sign the paperwork and are legally married. Weall definitely be crossing that bridge first to keep the house thing simpler.
