Financial Infidelity

Today my world fell apart! My ADHD husband has basically lost everything we own and most likely have to declare bankruptcy. He has been lying about his business and our own personal finances and has dug himself and  our family into a black hole.

At 55 years I will have nothing. I was stupid enough to leave the finances to him as he always moved things around and knew what money was coming in based on the business. He never paid himself a weekly salary. 

I have forgiven his past white lies about money hoping things would improve ( he always said he had it handled). He has had past failures and big wins in business - he's a big risk taker and fails to understand the impact his decisions and actions have on me and the family. This is when the lie occurs. If I'd question a decision he would weave a story to make it sound so good. 

He has spent years in therapy for ADHD, depression etc. and is on meds but ultimately his behaviour has damaged all his relationships and our marriage. I have no trust in him and don't know if we can survive this as a family and move forward together.

ADHD is a huge impact on his behavior but I don't know how much more I can take. I worry for his mental health if I walk as I manage the day to day of his life (constantly reminding him to do things, keeping the house in some sort of order, reminding him of appointments etc) and creating a form of stability. 

My question is, will it ever change? Or is this life with someone with ADHD? I also have a son who is exactly the same... I'm exhausted.
