I was thinking about either adding a second checking for her OR making her use her CC for everything and then just paying the balance every month. What do you guys do?  <response>: have 3 accounts instead. person 1, person 2, joint.All the major shared stuff comes out of the joint account.all personal purchases comes out of each persons respective individual account.decide as a couple how much spending cash each person gets every month.
