> What impact has having such clear visibility into your accounts had on your relationship with your wife?

That's a great question. Thankfully when it comes to finances we are very aligned in our habits and goals. So we find it very natural to be open because we know that we're both going to be aligned.

Where we differ heavily though is how much we are willing to really getting onto the nitty gritty details. She really likes knowing how our money works but she also has no interest in spending so much time and effort on it.

But that works great because I love this stuff. So every month or so we have a "finances session" where I sit down with her, take her through the books and make sure we're both happy with everything.

Obviously this very much depends on the couple whether this works but it has for us so far!
