I think it is great that you found out that both financial and communication are the hot topics. And yes, those two things you CAN work on.
of course, do understand that a vast majority of marital problems are financial and communication based.
That being said, what can you do regarding changing yourself around the financial aspects? What PART of financial is your W concerned about?
Also, when someone suggests that communication is a problem, it can often be because they feel they are not being heard. How can you support better communication with your W?
