I've left negative trust.
I doubt he wants to ruin his reputation for that amount so let's hope he'll eventually repay. Although the fact he hasn't contacted you in several weeks is a very bad sign :/
Probably this thread and the negative trust he'll receive will help get your money back.
Thanks. I understand that he was fairly late with one or two loans in the past, and I am hoping that this is a similar situation. I believe that he fairly quickly repaid the other lender(s) after they called him out publicly on him defaulting.
