<prompt> Human: Im moving in with my girlfriend of about a year, were both in our latemid twenties. I was wondering what a good way to split expenses would be?I was thinking about a joint credit card that way we get the points. I trust her enough not to go on a spending spree with the card.Thoughts?Edit: I was thinking of just doing it for ease. How do you split communal expenses such as groceries?  <response>: Nobody here would suggest a joint credit card, for legal and liability reasons. That would only be suggested to a married couple. You two should split expenses however the two of you feel is fair. Sit down, talk about all the expenses, make decisions that youre both comfortable with - and continue to COMMUNICATE with each other. Dont let issues turn into fights because you try ignoring things until its too late. But asking US how you should handle your expenses wont make either of you ok with something that youre not ok with - and only the two of you know what youre okay with..
