Non ADHD Spouse Looking for Help

Hi there my name is Mary and I have been married to my spouse for 4.5 years, together for almost 7. He was diagnosed with ADHD a couple years back and it's been tough. Right now he is on a business venture to start a Marijuana grow, which has been in progress for over two years now, with little progress made, and lots of money spent. He lacks the ability to focus and stay on task, and it's impacting our marriage. I feel resentful over it because I feel like this business is destroying our marriage, but it's also his dream and I don't want to negatively impact that. Our finances are a mess, our house is a disaster, and he keeps spending more money on stuff for this business. 

His other issues include mood swings, he gets super angry and throws things (never at me though), he can't sleep at night, and he is full of numerous ideas and plans that are super unrealistic. 

Any tips or tricks on how to navigate this would be super appreciated. I am so stressed and overwhelmed, and I feel like I'm walking on egg shells. 

 

Thanks in advance.
