Unemployed Husbands Loans And Transactions

if you know, my second marriage is also on the rocks. Married 7 months ago. separated for 3 months now.
So, what came to light after marriage is his temper, his ED. I knew he was uneducated, unemployed but his health was ok so thought thats fine for this age.

Next his statements show a series of people giving him money starting 2 months of marriage. I sent him to his house. I asked to meet to try and reconcile and apparently, he "helped" a friend to save some taxes by "taking" 30 lakhs from a friend to his account and returning to his friends account in 2-3 days? Isnt this some sort of money laundering? Is this even legal? Shouldnt he be not doing this?

What are repurcussions that I have to face if I even take him back? (I am employed, own my own property. We dont have anything joint)
