Husband owes me close to $100,000.

Rant: My husband is 13 years older than me and earns at least 3 to 4x of my current salary. I lend him a few thousands 5 to 6 years back for house renovation (i was 23 years old then and i told him that i can't afford any costs when it comes to marriage & kids as I have only just graduated), yet until today he has not returned me the full sum yet. Subsequently, he tried to get me to invest my savings instead of putting it with the bank for higher interests. I transferred a huge sum to him and now that i wanted the whole sum to be transferred to me back, he kicked up a big fuss and threatened to divorce. I feel so helpless. Lend him money yet must beg him to return as though I am at his mercy. I don't know what to do.
