I'm guessing here but it looks to me like this is the same MLC returned from 2013. MLC in men takes 5 - 7 years to complete and maybe longer. He was gone for only 4 months in 2013. Rarely do such returns last before they have to get back to resolving those hidden issues deep inside.
I'm sorry to hear about your health issues and hope you recover soon. The MLCer really doesn't have much compassion while deep in the crisis. It's unfortunately just part of the condition.
Finances - it would be critical to lock the finances down so he can't spend your savings too. Not easy to do though unless you see a lawyer for a separation agreement.
