How to change my vision/relationship with money?


I have never been money driven but I have also allowed my husband to manage our finances. I am not a big spender but live comfortably. However, now that my husband is in his 60’s and having some health issues I may have a compelling reason to begin to learn about our finances. I’m not sure how to begin or whether or not I should worry? Honestly, I’m a survivor and have always figured everything out as it comes. However, I do pride myself on proactivation in most all aspects of my life, except for money. So my question is how do I begin feeling more comfortable about my future since I’m planning on living another 50+years. I have lots to still accomplish. How do I change my vision of money and feel comfortable talking about it.
