Reason why An Jae Hwan committed suicide

It was holiday here yesterday so while I was watching tv, I saw the news about the death of An Jae Hwan. No one expected that he would commit suicide because he always showed on tv with smile on his face. No one also expected that his debt reached up to $4million, the money that he used for his bankrupted cosmetics business. The reason why he committed suicide. Do you think his wife (Jeong Seon Hui) is responsible of his debt eventhough their marriage contract wasn't registered? They have been married for less than a year and he had those debts before they got married. Actually, there's no issue about it but i'm just curious.
